Chris Wilson 6cc32f15f9 drm/i915/gt: Reorganise gen8+ interrupt handler
We always use a deferred bottom-half (either tasklet or irq_work) for
processing the response to an interrupt which means we can recombine the
GT irq ack+handler into one. This simplicity is important in later
patches as we will need to handle and then ack multiple interrupt levels
before acking the GT and master interrupts.
