drm/i915: irq handlers don't need interrupt-safe spinlocks

Browse source

Since we only have one interrupt handler and interrupt handlers are
non-reentrant.

To drive the point really home give them all an _irq_handler suffix.

This is a tiny micro-optimization but even more important it makes it
clearer what locking we actually need. And in case someone screws this
up: lockdep will catch hardirq vs. other context deadlocks.

v2: Fix up compile fail.
