The relation of i2s nodes as follows:
i2s_src 0 0 594000000 0
i2s_frac 0 0 11289600 0
i2s_pre 0 0 11289600 0
sclk_i2s0 0 0 11289600 0
i2s0_clkout 0 0 11289600 0
hclk_i2s0 1 1 99000000 0
sclk_i2s0 is the master clock, when to set rate of sclk_i2s0, should
allow to set its parent's rate, by add flag CLK_SET_RATE_PARENT for
"i2s_frac", "i2s_pre", "i2s0_clkout" and "sclk_i2s0".
Tested on rk3288 board using max98090, with command "aplay <music.wav>"

This adds the necessary soc-specific divider values and switches the armclk
to use the newly introduced cpuclk type.

Rockchip SoCs contain clocks tightly bound to the armclk, where the best
rate / divider is supplied by the vendor after careful measuring.
Often this ideal rate may be greater than the current rate.
Therefore prevent the ccf from trying to set these dividers itself by
setting them to read-only.
In the case of the rk3066, this also includes the aclk_cpu, which makes it
necessary to also split its direct child-clocks (pclk_cpu, hclk_cpu, ...)
into individual definitions for rk3066 and rk3188.

In RK3288, APLL lock status bit is in GRF_SOC_STATUS1,
but in RK3188, is GRFSOC_STATUS0.

Also name the constant accordingly as GRF_SOC_STATUS1
to prevent confusion.

The npll on rk3288 is exactly the same pll type as the other 4. Yet it
was missing the link to the rate table, making rate changes impossible.
Change that by setting the table.

The dwc2 usb controller also uses agressive clock gating, which in this
case leads to hclk_peri getting disabled and hanging the system.
Therefore move it to the critical clocks until we also control that
part of the system.

The clocks for i2c1 and i2c2 are flipped. The clock tree matched the
Technical Reference Manual (TRM) but the TRM was wrong. Swap them in
the clock tree. This was determined experimentally (by Addy) and
confirmed by the Rockchip IC team.

The clock-tree contains clocks that should never get disabled automatically.
One example are the base ACLKs, the base supplies for all peripherals.
Therefore add a structure similar to the sunxi clock-tree to protect these
special clocks from being disabled.
