drm/xe: Always setup GT MMIO adjustment data

[ Upstream commit bbd8429264baf8bc3c40cefda048560ae0eb7890 ]

While we believed that xe_gt_mmio_init() will be called just once
per GT, this might not be a case due to some tweaks that need to
performed by the VF driver during early probe.  To avoid leaving
any stale data in case of the re-run, reset the GT MMIO adjustment
data for the non-media GT case.
