[Intel-gfx] [PATCH v3 3/5] drm/i915: make sure correct pte encode is used

From: Fei Yang <fei.yang at intel.com>

PTE encode is platform dependent. After replacing cache_level with
pat_index, the newly introduced mtl_pte_encode is actually generic
for all gen12 platforms, thus rename it to gen12_pte_encode and
apply it to all gen12 platforms.
