drm/xe: Introduce has_atomic_enable_pte_bit device info

Add has_atomic_enable_pte_bit to specify that a device
has PTE_AE bit in its PTE feild. Currently XE2 and PVC
supports this so set this for those two.

This will help consolidate setting atomic access bit in PTE
logic which is spread between multiple files.
