[Intel-xe] [PATCH v3 3/7] drm/xe/pat: trim the tgl PAT table

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

We don't seem to use the 4-7 pat indexes, even though they are defined
by the HW. In the next patch userspace will be able to directly set the
pat_index as part of vm_bind and we don't want to allow setting 4-7.
Simplest is to just ignore them here.
