drm/i915/bw: Deduplicate intel_sa_info instances

Now that intel_sa_info contains bandwidth parameters specific to the
display IP, we can drop many duplicates and reuse from previous
releases.

Let's do that and also simplify intel_bw_init_hw() while at it.

v2:
  - Drop rkl_sa_info and reuse icl_sa_info. (Matt)
  - Add comment explaining RKL's display's peculiarity on using ICL's
    parameters. (Matt)
  - Don't rename xelpdp_sa_info to mtl_sa_info.  Renaming of instances
    to use IP names will be done in upcoming changes.
