drm/xe/rtp: Add match helper for gslice fused off

Browse source

Add match helper to detect when the first gslice is fused off, as needed
by future workarounds.

v2:
  - Add warning if called on a platform without geometry pipeline
    (Matt Roper)
  - Hardcode 4 as the number of gslices, which matches all the currently
    supported platforms. PVC doesn't have geometry pipeline and
    shouldn't use this function (Matt Roper)
