This series is an attempt to address multiple issues with DSC,
scattered in separate existing series.

Patches 1-4 are DSC fixes from series to Handle BPC for HDMI2.1 PCON
https://patchwork.freedesktop.org/series/107550/

Patches 5-6 are from series DSC fixes for Bigjoiner:
https://patchwork.freedesktop.org/series/115773/

Patches 7-17 are based on series to add DSC fractional BPP support:
https://patchwork.freedesktop.org/series/111391/

Patch 18 is to fix compressed bpc for MST DSC, from Stan's series :
https://patchwork.freedesktop.org/series/116179/

Rev2: Addressed review comments from Stan, Ville.

Rev3: Split larger patches. Separate out common helpers.

Rev4: Rebased, fixed checkpatch warnings.

Rev5: Addressed review comments from Stan.
Added a patch to check if forced dsc format can be used before forcing.
