Structure, exposed via HF-VSDB or HF-SCDB. The actual content
of the them is same. So it needs only one parse function.

When the dsc bpp is less than 9, hdmi output will flash on TV.
It is speculated that the reason is that pixel rate of sink
decoding is not enough.
Taking 8bpp as an example, dsc clk needs to be 1/3 of the input
clk.the theoretical calculation of DEN compression 1/3, at this
time, the clk of vop dsc to hdmi tx can be reduced to about 260M
to meet the 8bpp transmission.
RK3588 dsc clk only supports 1/2 frequency division, so dsc clk
is 1/2 input clk, which needs to increase blank, which is
equivalent to compressing the absolute DEN time. TV is likely to
decode at a decoding rate of around 260M. DEN absolute time
shortening results in abnormal TV decoding.
So the value of hblank needs to be reduced when bpp is below 9.
The measurement can be displayed normally on TV, but reducing
the hblank will result in non-standard timing of the hdmi output.
This may cause compatibility issues and hdmi cts certification
may fail.

In order to cover more application scenarios, when the crtc changes,
the old output_if should be cleared, rather than when the flag
&drm_crtc_state.active_changed is set to 1.
In addition, it would be more reasonable to name new crtc to 'new_crtc'
rather than 'crtc'.

It makes sense to check whether the assigned cursor plane can be
attached to a specific VP, as there may be an invalid DTS assignment
for 'cursor-win-id'.

RK3528/RK3562/RK3576 use the VOP3 architecture, which supports
flexible switching of planes between different VP. User can switch
planes between different CRTCs based on the &drm_plane.possible_crtcs
in userspace, and the plane-mask does not need to be assigned by
default in DTS.
However, for some Linux systems, there may still be scenarios where
it is necessary to specify the primary and cursor planes specifically
used on a VP.
Therefore, the valid plane-mask assignment will change the
&drm_plane.possible_crtcs and establish a fixed binding relationship
between planes and CRTCs, which means that the flexible switching of
planes is not available in the case.
