drm/i915: refactor skylake scaler code into new file.

This moves the code from various places and consolidates it
into one new file.

v2:
- rename skl_program_plane -> skl_program_plane_scaler (Ville)
- also move skl_pfit_enable, and consequently make some skl_scaler_*
  functions static to skl_scaler.c (Ville)
