drm/i915/dp: Rename some variables in xelpd_dsc_compute_link_config()

Use the _x16 suffix for all .4 fixed point variables. Drop compressed_
prefix, as it's implied from the precision suffix.

As dsc_min_bpp and dsc_max_bpp change domain from int to .4 in the
middle of the function, they remain the same for now.
