[0/7] DP DSC min/max src bpc fixes

Message

Nautiyal, Ankit K Oct. 3, 2024, 10:43 a.m. UTC

Use helpers for source min/max src bpc appropriately for dp mst case and
to limit max_requested_bpc property min/max values. 

Rev2: Dropped patch to limit max_requested_bpc based on src DSC bpc
limits. Instead added change to ignore max_requested_bpc if its
too low for DSC.

Rev3: Updated patch#1 commit message.

Rev4: Rebase.

Rev5: Addressed Jani's comment on patch#3.

Rev6: Rebase.

Rev7: Added patch to fix return type for dsc_min/max_src bpc helpers to
int.

Rev8: Drop the first patch and added patches to refactor pipe_bpp limits
and link limits.
