drm/xe: Stop tracking 4-tile support

Browse Source 
The choice of Y-major tiling format (either the legacy "TileY" or the
newer "Tile4") is based on graphics IP version (12.50 and beyond have
Tile4, earlier platforms have TileY).  The tracking in xe was originally
added to allow re-using display from i915.  However as of i915 commit
4ebf43d0488f ("drm/i915: Eliminate has_4tile feature flag"), the display
code determines TileY vs Tile4 itself, so this can be removed from xe.
