Was tipped off to this bit downstream where if DSC is enabled and panel uses
RGB101010, it overrides back to RGB888:
https://git.codelinaro.org/clo/la/platform/vendor/opensource/display-drivers/-/blob/DISPLAY.LA.4.0.r2-10000-lanai.0/msm/dsi/dsi_display.c?ref_type=tags#L7209

Only does this if widebus isn't also enabled though. Should we do this as well
upstream?

Thanks,
