drm/xe/oa/uapi: Define and parse OA sync properties
[ Upstream commit c8507a25cebd179db935dd266a33c51bef1b1e80 ]
Now that we have laid the groundwork, introduce OA sync properties in the
uapi and parse the input xe_sync array as is done elsewhere in the
driver. Also add DRM_XE_OA_CAPS_SYNCS bit in OA capabilities for userspace.
v2: Fix and document DRM_XE_SYNC_TYPE_USER_FENCE for OA (Matt B)
Add DRM_XE_OA_CAPS_SYNCS bit to OA capabilities (Jose)
