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