drm/xe/oa/uapi: Expose media OA units
On Xe2+ platforms, media engines are attached to "SCMI" OA media (OAM)
units. One or more SCMI OAM units might be present on a platform. In
addition there is another OAM unit for global events, called
OAM-SAG. Performance metrics for media workloads can be obtained from these
OAM units, similar to OAG.
Expose these OAM units for userspace to use. OAM-SAG is exposed as an OA
unit without any attached engines.
Bspec: 70819, 67103, 63844, 72572, 74476, 61284
v2: Fix xe_gt_WARN_ON in __hwe_oam_unit for < 12.7 platforms
v3: Return XE_OA_UNIT_INVALID for < 12.7 to indicate no OAM units
v4: Move xe_oa_print_oa_units() to separate patch
v5: Introduce DRM_XE_OA_UNIT_TYPE_OAM_SAG
v6: Introduce DRM_XE_OA_CAPS_OAM
