drm/i915/display: convert the display irq interfaces to struct intel_display

drm/i915/display: convert the display irq interfaces to struct intel_display

Convert the irq/error init/reset interfaces from struct intel_uncore to
struct intel_display, and drop the dependency on intel_uncore.h.

Since the intel_de_*() calls handle the DMC wakelock internally, we can
drop the wrappers handling wakelocks completely.
