[PATCH 3/4] drm/xe: Annotate multiple mmio pointers with __iomem

[Thomas Hellström]

There are a couple of pointers pointing to MMIO space. Annotate them
with __iomem and fix the corresponding sparse warnings.

Fixes: dd08ebf6c352 ("drm/xe: Introduce a new DRM driver for Intel GPUs")
Fixes: 3b0d4a557996 ("drm/xe: Move register MMIO into xe_tile")
Fixes: 399a13323f0d ("drm/xe: add 28-bit address support in struct xe_reg")
