If i2c slave devices don't work at the same time, which have
the same i2c addr, this patch can make them working.

If the system rebooted, there might be i2c transfer at the
same time, it will make something unpredictable, because
the i2c host was reset, but the slave device wasn't, such
as rk808 pmic, so make sure the i2c transfer to be finished
before system shutdown at the reset mode.
This call chain is expected to be executed before kernel_restart
to do something before reset system. such as, i2c restart,
boot mode config.

If the referenced regulator is a dummy, the voltage is invalid,
but someone doesn't need the voltage, just need the adc value,
so don't return fail at probe when the regulator is dummy. If
he wants the voltage, configures the actual referenced regulator
at dts.

As a second global reset, the GRF is not reset, the iomux and
pull of PWM pin is still keeping, but PWM controller is reset,
PWM pin goes into input mode. However, the pull is still none
changed in kernel, which can cause voltage problems, so should
always keep the PWM pin pull down mode, with 0~50 μA power
increase.

If the PWM pinctrl uses default state, the iomux setting will
be done at probe, the PWM may not be enabled at this moment.
It will make PWM into an intermediate state, destroy the default
hardware state, the PWM is not ready for work yet. So it is better
for doing PWM pinctrl setting after PWM enabled.

This patch is based on https://patchwork.kernel.org/patch/9801533,
add the drm property "hdmi_output_format", the possible value
could be:
- RGB
- YCBCR 444
- YCBCR 422
To handle various subsampling of YCBCR output types, this property
allows two special automatic cases:
- DRM_HDMI_OUTPUT_YCBCR_HQ
This indicates preferred output should be YCBCR output,
with highest subsampling rate by the source/sink, which
can be typically:
- ycbcr444
- ycbcr422
- ycbcr420
- DRM_HDMI_OUTPUT_YCBCR_LQ
This indicates preferred output should be YCBCR output, with
lowest subsampling rate supported by source/sink, which can be:
- ycbcr420
- ycbcr422
- ycbcr444
Default value of the property is set to 0 = RGB, so no changes if you
don't set the property.

This patch introduce a drm property hdmi_output_depth to
get/set HDMI color depth, the possible value could be
- Automatic
This indicates prefer highest color depth, it is
30bit on rockcip platform.
- 24bit
- 30bit
The default value of property is 24bit.
The max_tmds_clock is 0 on some display device, we think it's
max_tmds_clock is 340MHz.
If tmdsclock > max_tmds_clock, real output color depth fallback
to 24bit.
