drm/xe: Clarify 'gt' retrieval for primary tile

Browse source

There are a bunch of places in the driver where we need to perform
non-GT MMIO against the platform's primary tile (display code, top-level
interrupt enable/disable, driver initialization, etc.).  Rename
'to_gt()' to 'xe_primary_mmio_gt()' to clarify that we're trying to get
a primary MMIO handle for these top-level operations.

In the future we need to move away from xe_gt as the target for MMIO
operations (most of which are completely unrelated to GT).

v2:
 - s/xe_primary_mmio_gt/xe_root_mmio_gt/ for more consistency with how
   we refer to tile 0.  (Lucas)
v3:
 - Tweak comment on xe_root_mmio_gt().  (Lucas)
