Vcnt is stored in the upper 16 bits.
We should wait for the frame start irq status from
low to high.

frame start of previous vp")

isp2.0 one frame read back many times and gain
address will updated at each read back end. To make
sure gain buffer update right, so one last read back
to the frame start to config next buf, and the frame end
will update to shadow reg for ready to receive next frame.

tips:
1. rcb_size == 0, skip it.
2. if current rcb_size is larger then the remaining buffer size,
skip it instead of break.

This patch add uevent to notify the application layer how much ppm
is different between USB clk and AUDIO clk.
The event include two parts USB_STATE and PPM. For example:
g_audio_work: sent uac uevent USB_STATE=SET_AUDIO_CLK PPM=12
g_audio_work: sent uac uevent USB_STATE=SET_AUDIO_CLK PPM=-1
Note: The ppm compensation depends on the method implement of
clk drift and compensation in the rockchip_pdm.c driver. So if
you want the ppm compensation to take effect, please make sure
the commit "ASoC: rockchip: pdm: Add support for clk compensation"
is merged.

Only config done the current vp at the first 3/4 frame time

The config done bits of VP0, VP1, VP2 on RK3568 stands on
the first three bits on REG_CFG_DONE register without mask bit.
If two or three config done events happens one after
another in a very shot time, the flowing config done
write may override the previous config done bit before
it take effect:
1: config done 0x8001 for VP0
2: config done 0x8002 for VP1
0x8002 may override 0x8001 before it take effect.
So we do a read | write here.

This patch renames kernel_i2c_restart to kernel_pre_restart
for general purpose.
This call chain is expected to be executed before kernel_restart
to do something before reset system. such as, i2c restart,
boot mode config.
