[Intel-xe] [PATCH v12 07/13] drm/xe/pci: wrap probe with mem_access

[Matthew Auld <matthew.auld@intel.com>]

Various display init stuff is missing mem_access.ref, so just wrap the
entire probe sequence with xe_device_mem_access_get(). It's impossible
for the device to actually be runtime suspended during probe, so this is
purely just to stop the xe_device_assert_mem_access() from incorrectly
firing. In a later patch we want to add xe_device_assert_mem_access()
for all mmio accesses.
