drm/i915/dp: Consider output_format while computing dsc bpp
While using DSC the compressed bpp is computed assuming RGB output
format. Consider the output_format and compute the compressed bpp
during mode valid and compute config steps.
For DP-MST we currently use RGB output format only, so continue
using RGB while computing compressed bpp for MST case.
v2: Use output_bpp instead for pipe_bpp to clamp compressed_bpp. (Ville)
