[Intel-gfx] [PATCH] drm/i915: limit PM related interrupt enable to those we handle

Set both the PM core interrupt regs and the PM specific interrupt maks to only allow interrupts we handle. This prevents spurious interrupts and just makes more sense. v2: use a mask for the mask reg Signed-off-by: Jesse Barnes --- drivers/gpu/drm/i915/i915_reg.h |6 ++ drivers/gp
