[PATCH 11/13] drm/i915/dp: Rename helpers to get DSC max pipe_bpp/output_bpp

[Ankit Nautiyal]

Currently the required dsc output bpp is set to be the largest
compressed bpp supported for max, lane, rate, and bpp.
The helper intel_dp_dsc_get_output_bpp gets the maximum supported
compressed bpp taking into account link configuration, input bpp,
bigjoiner considerations etc.

Similarly, the helper intel_dp_dsc_compute_bpp gives the maximum
pipe bpp that is allowed with DSC.

Rename the functions to reflect that these return max DSC input and
output bpps.
