Most of MMIO accesses from intel_display_irq.c are currently done via uncore_*() functions instead of the display-specific ones, namely intel_de_*(). Because of that, DMC wakelock ends up being ignored and some invalid MMIO accesses are performed while display is in dynamic DC states. Thus, update the display IRQ code to use the intel_de_*() MMIO functions. After this change, we are left with some IRQ-specific functions that still use the unwrapped uncore_*() functions (i.e. gen2_irq_init, gen3_irq_reset and gen2_assert_iir_is_zero). We will deal with them in an upcoming change.
