[Intel-gfx] [PATCH 1/5] drm/i915/crt: split out intel_crt_present() to platform specific setup

With new platforms not having CRT support and most conditions in
intel_crt_present() being specific to DDI, split out the CRT
initialization to platform specific blocks in the if ladder. Add new
Pineview block for this.
This puts intel_crt_init() more in line with the rest of the outputs,
and makes it slightly easier for the uninitiated to figure out which
platforms actually have what.
