drm/xe: Return 2MB page size for compact 64k PTEs

Browse source

Compact 64k PTEs are only intended to be used within a single VMA which
covers the entire 2MB range of the compact 64k PTEs. Add
XE_VMA_PTE_COMPACT VMA flag to indicate compact 64k PTEs are used and
update xe_vma_max_pte_size to return at least 2MB if set.

v2: Include missing changes

Fixes: 8f33b4f054 ("drm/xe: Avoid doing rebinds")
Fixes: c47794bdd6 ("drm/xe: Set max pte size when skipping rebinds")
