Subject: drm/i915/gt: Tidy repetition in declaring gen8+ interrupts
Git-commit: ff3d4ff6c9e66ba1602d0b89255961ddd43e7db7
Patch-mainline: v5.7-rc1
References: jsc#SLE-12680, jsc#SLE-12880, jsc#SLE-12882, jsc#SLE-12883, jsc#SLE-13496, jsc#SLE-15322
We use the same interrupt mask for each engine, so define it once in a
local and reuse.
