When we hook up interrupts (in the next patch), interrupts for the media
GT are still processed as part of the primary GT's interrupt flow. As
such, we should share the same IRQ lock with the primary GT. Let's
convert gt->irq_lock into a pointer and just point the media GT's
instance at the same lock the primary GT is using.
v2:
- Point media's gt->irq_lock at the primary GT lock properly. (Daniele)
- Fix jump target for intel_root_gt_init_early errors. (Daniele)

This is a huge, chaotic mass of registers copied over as-is without any
real cleanup. We'll come back and organize these better, align on
consistent coding style, remove dead code, etc. in separate patches
later that will be easier to review.
v2:
- Add missing include in intel_pxp_irq.c
v3:
- Correct a few indentation errors (Lucas)
- Minor conflict resolution

It also takes care of renaming the variable we assign to GRAPHICS_VER()
so to use "ver" rather than "gen".

i915_irq.c is large. It serves as the central dispatch and handler for
all of our device interrupts. Lets break it up by pulling out the GT
interrupt handlers.

i915_irq.c is large. It serves as the central dispatch and handler for
all of our device interrupts. Pull out the GT pm interrupt handling
(leaving the central dispatch) so that we can encapsulate the logic a
little better.
