drm/xe/pat: trim the xelp PAT table

Browse source

We don't seem to use the 4-7 pat indexes, even though they are defined
by the HW. In a future 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.
