The different submission backends each have their own preferred
behaviour and interrupt setup. Let each handle their own interrupts.
This becomes more useful later as we to extract the use of auxiliary
state in the interrupt handler that is backend specific.

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.

i915_irq.c is large. It serves as the central dispatch and handler for
all of our device interrupts. Lets break it up by pulling out the GT
interrupt handlers.
Based on a patch by Chris Wilson.
