drm/xe/pf: Program LMTT directory pointer on all GTs within a tile

Browse source

[ Upstream commit ad69d62588 ]

Previously, the LMTT directory pointer was only programmed for primary GT
within a tile. However, to ensure correct Local Memory access by VFs,
the LMTT configuration must be programmed on all GTs within the tile.
Lets program the LMTT directory pointer on every GT of the tile
to guarantee proper LMEM access across all GTs on VFs.
