drm/xe: Adjust mmio code to pass VF substructure to SRIOV code

Browse source

[ Upstream commit 6fb5d1a1d3 ]

Although we want to break the GT-centric nature of the MMIO code in the
general driver, the SRIOV handling still relies on data in a VF
substructure of the GT.  So add a GT backpointer, but name it
sriov_vf_gt to make it clear that it's only for this one specific
special case and will not be set or usable for anything else.

v2:
 - Store backpointer to the GT itself rather than the SRIOV-specific
   substructure.  (Michal)
