Following the removal of the clk_regmap clock table from the s4-peripherals
clock controller driver, it appears some clocks are unused, which means
these are not exported or even registered.
In all likelihood, these clocks have not been tested. Remove the unused
clocks for now. These can added back later when they have been properly
tested.

Remove the clk_regmap tables that are used to keep track which clock
need to be initialised before being registered. The initialisation is now
done by the .init() operation of clk_regmap.
This rework saves a bit memory and makes maintenance a bit easier.

Add clk_regmap_init() and use it with all clock types which derive from
clk_regmap. This helps initialise clk_regmap clocks without requiring
tables to keep track of the clock using this type.
The way it is done couples clk_regmap with the controllers, which is not
ideal. This is a temporary solution to get rid of the tables. The situation
will eventually be improved.

Some Amlogic clock controller drivers have a dedicated headers file, some
do not. Over time, these headers have evolved and now only carry register
offset definitions. These offsets are only used by the related controller
and are not meant to be shared.
These headers are not serving any purpose now.
Start enforcing some consistency between the different Amlogic clock
drivers and move the register offset definitions to the related driver.

SPICC is missing fclk_div2, which means fclk_div5 and fclk_div7 indexes
are wrong on this clock. This causes the spicc module to output sclk at
2.5x the expected rate when clock index 3 is picked.
Adding the missing fclk_div2 resolves this.

The 32k clock reference a parent 'cts_slow_oscin' with a fixme note saying
that this clock should be provided by AO controller.
The HW probably has this clock but it does not exist at the moment in
any controller implementation. Furthermore, referencing clock by the global
name should be avoided whenever possible.
There is no reason to keep this hack around, at least for now.

gxbb_32k_clk_div sets CLK_DIVIDER_ROUND_CLOSEST in the init_data flag which
is incorrect. This is field is not where the divider flags belong.
Thankfully, CLK_DIVIDER_ROUND_CLOSEST maps to bit 4 which is an unused
clock flag, so there is no unintended consequence to this error.
Effectively, the clock has been used without CLK_DIVIDER_ROUND_CLOSEST
so far, so just drop it.

Several clocks used by both g12a and g12b use the g12a cpu A clock hw
pointer as clock parent. This is incorrect on g12b since the parents of
cluster A cpu clock are different. Also the hw clock provided as parent to
these children is not even registered clock on g12b.
Fix the problem by reverting to the global namespace and let CCF pick
the appropriate, as it is already done for other clocks, such as
cpu_clk_trace_div.

The bit index of the peripheral clock for mmc A is wrong
This was probably not a problem for mmc A as the peripheral is likely left
enabled by the bootloader.
No issues has been reported so far but it could be a problem, most likely
some form of conflict between the ethernet and mmc A clock, breaking
ethernet on init.
Use the value provided by the documentation for mmc A before this
becomes an actual problem.

clk_set_rate() because it led to problems with the Qualcomm CPUFreq

- Revert Amlogic reset driver back to the initial implementation.

The audio subsystem of axg based platform is not probing anymore.
This is due to the introduction of RESET_MESON_AUX and the config
not being enabled with the default arm64 defconfig.
This brought another discussion around proper decoupling between
the clock and reset part. While this discussion gets sorted out,
revert back to the initial implementation.

The fixed_pll_dco output frequency is not accurate,
add frac factor for fixed_pll_dco clk to fix it.

Add MODULE_DEVICE_TABLE(), so modules could be properly autoloaded
based on the alias from of_device_id table. Clocks are considered core
components, so usually they are built-in, however these can be built and
used as modules on some generic kernel.

In order to setup the DSI clock, let's make the unused VCLK2 clock path
configuration via CCF.
The nocache option is removed from following clocks:
- vclk2_sel
- vclk2_input
- vclk2_div
- vclk2
- vclk_div1
- vclk2_div2_en
- vclk2_div4_en
- vclk2_div6_en
- vclk2_div12_en
- vclk2_div2
- vclk2_div4
- vclk2_div6
- vclk2_div12
- cts_encl_sel
vclk2 and vclk2_div uses the newly introduced vclk regmap driver
to handle the enable and reset bits.
In order to set a rate on cts_encl via the vclk2 clock path,
the NO_REPARENT flag is set on cts_encl_sel & vclk2_sel in order
to keep CCF from selection a parent.
The parents of cts_encl_sel & vclk2_sel are expected to be defined
in DT or manually set by the display driver at some point.
The following clock scheme is to be used for DSI:
xtal
\_ gp0_pll_dco
\_ gp0_pll
|- vclk2_sel
| \_ vclk2_input
| \_ vclk2_div
| \_ vclk2
| \_ vclk2_div1
| \_ cts_encl_sel
| \_ cts_encl -> to VPU LCD Encoder
|- mipi_dsi_pxclk_sel
\_ mipi_dsi_pxclk_div
\_ mipi_dsi_pxclk -> to DSI controller
The mipi_dsi_pxclk_div is set as bypass with a single /1 entry in div_table
in order to use the same GP0 for mipi_dsi_pxclk and vclk2_input.
The SET_RATE_PARENT is only set on the mipi_dsi_pxclk_sel clock so the
DSI bitclock is the reference base clock to calculate the vclk2_div value
when pixel clock is set on the cts_encl endpoint.

The VCLK and VCLK_DIV clocks have supplementary bits.
The VCLK gate has a "SOFT RESET" bit to toggle after the whole
VCLK sub-tree rate has been set, this is implemented in
the gate enable callback.
The VCLK_DIV clocks as enable and reset bits used to disable
and reset the divider, associated with CLK_SET_RATE_GATE it ensures
the rate is set while the divider is disabled and in reset mode.
The VCLK_DIV enable bit isn't implemented as a gate since it's part
of the divider logic and vendor does this exact sequence to ensure
the divider is correctly set.

In most meson systems, multiple PLLs are present, making it difficult to
identify the specific PLL that fails to lock. To address this issue,
print out the name of the PLL that cannot be locked.
