drm/i915/display: pass struct intel_display to PCH macros

Now that INTEL_PCH_TYPE() and HAS_PCH_*() macros are under display, and
accept a struct intel_display pointer, use that instead of struct
drm_i915_private pointer in display code.

This is done naively by running:

$ sed -i 's/\(INTEL_PCH_TYPE\|HAS_PCH_[A-Z0-9_-]*\)([^)]*)/\1(display)/g' \
$(find drivers/gpu/drm/i915/display -name "*.c")

and fixing the fallout, i.e. removing unused local i915 variables and
adding display variables where needed.
