[Intel-gfx] [PATCH 3/11 v3] drm/i915: Extra media engines for ATS - Part 2 (interrupts)

[John.C.Harrison at Intel.com]

From: John Harrison <John.C.Harrison at Intel.com>

ATS has lots of extra media engines. This patch adds the interrupt
handler support for them.

v2: Changed debugfs to assume ATS always has VCSx8 + VECSx4
irrespective of fusings. [Tvrtko Ursulin]

v3: Changed interrupt masking to check for the presence of each pair
of engines to support fusings [Daniele].
