[Intel-xe] [PATCH 1/1] drm/xe: set PTE_AE for all platforms supporting it

[fei.yang@intel.com]

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

Atomic access is supported by PVC, and became a common feature for all
platforms starting from Xe2. To enable that XE_VMA_ATOMIC_PTE_BIT needs
to be set, then pte encode will eventually set PTE_AE for devmem.
