Test on RK3588S Tablet, set the power supply of logic on
and set the power supply of usb2 phy off during deep sleep,
then the id falling edge interrupt will be triggered after
system resume, and kernel panic with the following log:

In fact, there are two issues here.
1. The power of phy id belongs to the usb2 phy power supply.
And the id is pulled up to high level by default. So if we
power off usb2 phy supply during deep sleep, the id status
will fall to low level and trigger the falling edge interrupt.
In the id irq handler rockchip_usb2phy_id_irq(), it send Host
notification only depends the id falling edge irq status, it's
not enough in this case, it needs to check the iddig status
to make sure that the id status is indeed in low level.
2. For RK3588S, the pipe phystatus select register from the
usb grf, and the power domain of usb grf belongs to PD_USB.
So we must make sure the PD_USB is on when operate the pipe
phystatus select register. Originally, we operated the pipe
phystatus register in the phy ops of power_on, because we
expected that the phy ops of power_on called from the dwc3
controller pm runtime resume process which can power on the
PD_USB. However, in this test case, if the id falling edge
interrupt after system resume, the phy ops of power_on can
be called when PD_USB is off.
The call stack:
rockchip_usb2phy_id_irq()
-> send Host notification ->
rockchip_otg_event()
-> receive notification and schedule otg_sm_work ->
rockchip_usb2phy_otg_sm_work()
-> detect EXTCON_USB_HOST is set and call phy power_on ops
rockchip_usb2phy_power_on()
-> set the pipe phystatus select register

The configuration of flip/mirror would take effect in the half of frame,
which cause frame corruption. To make sure the flip/mirror configuration
is took effect in the next frame, we should enable register frame buffer
on gc4653.

The dsp_data_swap bits order may be different.
One is bg/rb/rg/delta/dummy, such as RK3288, RK3328

In VR application scenarios, some panel will realize dynamic frame
rate adjustment through a wide range of VFP settings, and VFP may
exceed the ip limit (0~1023), which may cause abnormal display. so
reject any modes with larger periods.

This patch allow users to enable "ELD Bypass" who don't
care anything from EDID Link Data.
Currently, this driver gets ELD(from EDID) to constraint
channels and rates.
Unfortunately, EDID is not always valid, maybe caused by
the fragile HDMI port or cable, in this situation, the max
features are limited to 48kHz stereo.
So, add this option to allow user to select the manual way
to output audio as expected. such as multi-channels LPCM(7.1),
or HBR bitstream for these sink devices.

Since the i2s does not support the clock to be always on, and
snd_pcm_stop() will turn off the i2s clock.
However, the inno HDMI codec still needs to the clock to work, then
it does not do the corresponding clear and leads to abnormal audio
logic inside HDMI without the clock.
This patch adds an AUDIO_PD off/on to clear internal audio logic
during HDMI prepare to solve this problem.
