drm fixes for 6.1-rc9

Browse source 
amdgpu:
 - S0ix fix
 - DCN 3.2 array out of bounds fix
 
 shmem:
 - Fixes to shmem-helper error paths.
 
 bridge:
 - Fix polarity bug in bridge/ti-sn65dsi86.
 
 dw-hdmi:
 - Prefer 8-bit RGB fallback before any YUV mode in dw-hdmi, since some
   panels lie about YUV support.
 
 vmwgfx:
 - Stop using screen objects when SEV is active.
