On the i.MX8M*, the TF-A exposes a SiP (Silicon Provider) service
for DDR frequency scaling. The imx8m-ddrc-devfreq driver calls the
SiP and then does clk_set_parent on the DDR muxes to synchronize
the clock tree.

Since 936c3836 ("clk: imx: fix composite peripheral flags"),
these TF-A managed muxes have SET_PARENT_GATE set, which results
in imx8m-ddrc-devfreq's clk_set_parent after SiP failing with -EBUSY:

clk_set_parent(dram_apb_src, sys1_pll_40m);(busfreq-imx8mq.c)

This is safe to do, because updating the Linux clock tree to reflect
reality will always be glitch-free.

Since 926bf912("clk: imx8m: fix clock tree update of TF-A
managed clocks"), it adds this method and enables 8mm, 8mn and 8mq. I
think 8mp is also needed.

Another reason I added this patch is that powersave image BT music
requires dram to be 400MTS, so clk_set_parent(dram_alt_src,
sys1_pll_800m); is required. Without this patch, it will not succeed.

evk_8mn will meet system hang when resume (using
"echo mem > /sys/power/state" to make system suspend
while display on).
The reason is that imx-drm driver resumes before
imx-lcdif driver, and access some hardware while
those resources not ready.

fw_devlink will affect the suspend/resume sequence
by parsing dts to create dependency btw drivers.
But these two drivers doesn't have supported dts
property for fw_devlink.

This patch explicitly defers the suspend sequence
of imx-lcdif driver to fix it.

The core and bus clocks are default enabled when SoC power on, and
bootloader not gate off the clocks when booting Linux Kernel.

So Linux Kernel is not aware the peripheral clocks are enabled and
still take them as disabled because of enable count is zero.

After we enable GKI, disable_unused_clk does not work. This causes
unused core and bus clocks to remain on, so turn them off here.

Current driver may meet reconfigure failure caused by below reasons:

1. The wdog on iMX7ULP has different behavior after RCS valid. It needs
   to wait more than 2.5 wdog clock for clock sync before next
   reconfiguration, while imx8ulp wdog does not need such delay.

2. After unlock, there is 128 bus clock window opened for reconfiguration,
   but on iMX8ULP, the HW can't guarantee the latency. So it is possible
   the window is closed before the writing arrives to wdog.

3. If the PRES is enabled, the RCS valid time becomes x256 to the time
   of PRES disabled. It is about 1715ms on iMX8ULP. So We have to increase
   the RCS timeout and can't wait it in IRQ disabled.

The patch updates the driver to handle failures

1. Using different wait for unlock and RCS. Unlock valid time is very short
   and only related to bus clock. It must be in IRQ disabled to avoid
   being interrupted in 128 clock window. But for RCS time, it is longer
   and ok for IRQ enabled.

2. Add retry for any reconfigure failure with default 5 times.

3. Add "fsl,imx8ulp-wdt" compatile string for iMX8ULP and afterwards
   platform which don't need more 2.5 wdog clock after RCS valid.
   For imx7ulp, add post delay of 2.5 clock after RCS valid.
