i.MX8MQ clock driver uses platform driver model, better to use

Some of i.MX SoCs' clock driver use platform driver model,
and they need to call imx_check_clocks() API, so
imx_check_clocks() API should NOT be in .init section.

We want to allow the parent lookup to happen even if the index is some
value less than 0. This may be the case if a clk provider only specifies
the .name member to match a string in the "clock-names" DT property. We
shouldn't require that the index be >= 0 to make this use case work.

Convert the boilerplate code for manual addition of the watchdog clock

Currently the default clock rates for the HDA and HDA2CODEC_2X clocks
are both 19.2MHz. However, the default rates for these clocks should
actually be 51MHz and 48MHz, respectively. The current clock settings
results in a distorted output during audio playback. Correct the default
clock rates for these clocks by specifying them in the clock init table
for Tegra210.

Some clk gates on Rockchip SoCs are part of the SGRF (secure general
register files) and thus only controllable from secure mode, with the
most prominent example being the watchdog.
In most cases we still want to define this as a real clock though,
to have complete clock tree and not reference the generic base-clock
from the devicetree.
So far we've just defined this as factor-1-1 clocks in the clock init,
so define a special clock-type for it so that this definition can be
part of the general tree-definition and save some boilerplate code.

Update the Meson G12A Clock driver to support the Amlogic G12B SoC.
G12B clock driver is very close, the main differences are :
- the clock tree is duplicated for the both clusters, and the
SYS_PLL are swapped between the clusters
- G12B has additional clocks like for CSI an other components
Here only the cpu clock tree is handled.

Add the cts_i958 clock to control the clock source of the spdif output
block. It is used to select whether the clock source of the spdif output
is cts_amclk (when data are taken from i2s buffer) or the cts_mclk_i958
(when data are taken from the spdif buffer). The setup for this clock is
identical to GXBB, so this ports commit 7eaa44f6207fb6 ("clk: meson:

The code was setting the bit 21 of the CPCCR register to use a divider
of 2 for the "pll half" clock, and clearing the bit to use a divider
of 1.
This is the opposite of how this register field works: a cleared bit
means that the /2 divider is used, and a set bit means that the divider
is 1.
Restore the correct behaviour using the newly introduced .div_table
field.

Some clocks provided on Ingenic SoCs have dividers, whose hardware value
as written in the register cannot be expressed as an affine function
to the actual divider value.
For instance, for the CPU clock on the JZ4770, the dividers are coded as
follows:
------------------
| Bits | Div |
------------------
| 0 0 0 | 1 |
| 0 0 1 | 2 |
| 0 1 0 | 3 |
| 0 1 1 | 4 |
| 1 0 0 | 6 |
| 1 0 1 | 8 |
| 1 1 0 | 12 |
------------------
To support this setup, we introduce a new field in the
ingenic_cgu_div_info structure that allows to specify the divider table.

Currently, the clock identifiers are limited to 255. To support future
SoCs, this muse be extended to 32 bits, which should provide way more
than enough space. Basic support for extending the clock API is going
to be implemented in the firmware driver, but there are some minor
changes that need to be done on the clock driver side first.

Probing all the available clocks from the PM firmware takes quite a lot
of time, increasing boot time. Instead, implement functionality that
parses only the used clocks from DT, and registers these to clock core.
This way, the boot time is greatly improved.
Additionally, provide a Kconfig option for parsing all the clocks from
firmware, if someone requires this. It is mostly useful as a debugging
functionality if we want to inspect the whole clock tree.
