drm/xe/mmio: Drop compatibility macros

Now that all parts of the driver have switched over to using xe_mmio for
direct register access, we can drop the compatibility macros that allow
continued xe_gt usage.

v2:
 - Move removal of 8/16-bit read and xe_mmio_wait32_not() wrappers to
   this patch rather than removing them in earlier patches when last
   caller was removed.  (Rodrigo)
