drm/amd/display: Cleanup DML DSC input bpc validation
[Why & How]
Pipe input DSC bpc has a type mismatch with maximum DSC
input bpc - align the maximum with the pipe input type,
unsigned integer.
When checking the type we shoudl also check for an
implicit value of 0 and align with what the spreadsheet
does - default to max.
Rename output_bpc to dsc_input_bpc to reflect what the
field is actually used for.
