[PATCH 1/2] drm/xe/pat: initialise pat.valid everywhere

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

We were only doing this for xe2+. However, having a central way
to determine if any index is reserved/valid will be useful later.
Currently we abuse checking coh_mode, which is a bit of a hack and can
be confusing.
