drm/i915/dpt: convert intel_dpt.[ch] interfaces to struct intel_display

Browse Source 
Going forward, struct intel_display is the main display device data
pointer. Convert the intel_dpt.[ch] interfaces to struct intel_display,
though the file being very i915 specific, it's hard to convert the
implementation.
