drm/xe/xe_exec_queue: Add check for access counter granularity
Add conditional check for access counter granularity.
This check will return -EINVAL if granularity is beyond 64M
which is a hardware limitation.
v2: Defined
XE_ACC_GRANULARITY_128K 0
XE_ACC_GRANULARITY_2M 1
XE_ACC_GRANULARITY_16M 2
XE_ACC_GRANULARITY_64M 3
as part of uAPI.
So, that user can also use it.(Oak)
v3: Move uAPI to proper location and give proper
documentation.(Brian, Oak)
