drm/xe: Move GSI offset adjustment fields into 'struct xe_mmio'

drm/xe: Move GSI offset adjustment fields into 'struct xe_mmio'

By moving the GSI adjustment fields into 'struct xe_mmio' we can replace
the GT's MMIO substructure with another instance of xe_mmio.  At the
moment this means MMIO operations wind up pulling information from two
different places (the tile's xe_mmio for the iomap and the GT's xe_mmio
for the adjustment), but we'll address that in future patches.

The type headers change a bit with this change, meaning that various
files should be including xe_device_types.h instead of (or in addition
to) xe_gt_types.h.

v2:
 - Fix pre-existing kerneldoc typo while moving the fields (Lucas)
v3:
 - Add missing '@' in kerneldoc.  (Rodrigo)
