drm/i915/crt: split out intel_crt_present() to platform specific setup

Browse Source 
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.

v2: keep gen >= 9 check in intel_ddi_crt_present() (Ville)
