[PATCH 0/2] drm/xe/pat: Type cleanup and invalid index hardening

[Xin Wang <x.wang@intel.com>]

Small follow-up series to harden the PAT subsystem:

Patch 1 fixes two remaining spots where pat_index was typed as u32/int
instead of u16, aligning with the rest of the driver.

Patch 2 defaults XE_CACHE_NONE_COMPRESSION to XE_PAT_INVALID_IDX (like
WB_COMPRESSION already does) and adds xe_assert() guards in xe_migrate
to catch any use on platforms that don't support it.

Suggested-by: Matthew Auld <matthew.auld@intel.com>

  drm/xe/pat: Default XE_CACHE_NONE_COMPRESSION to invalid and assert on
