drm/i915/mtl: Hook up interrupts for standalone media
Top-level handling of standalone media interrupts will be processed as
part of the primary GT's interrupt handler (since primary and media GTs
share an MMIO space, unlike remote tile setups). When we get down to
the point of handling engine interrupts, we need to take care to lookup
VCS and VECS engines in the media GT rather than the primary.
There are also a couple of additional "other" instance bits that
correspond to the media GT's GuC and media GT's power management
interrupts; we need to direct those to the media GT instance as well.
