Subject: [PATCH i-g-t v2 1/2] drm-uapi/amdgpu: Add queue priority and secure flags definitions

Add UAPI definitions for queue priority levels (NORMAL_LOW, LOW, etc.) and secure queue flag in amdgpu_drm.h. This matches the libdrm changes in commit fdf384d4b546 ("amdgpu: add priority and secure flags for user queues").

v2: In general, UAPI changes should be part of a different change and only uapi should be part of it (Sunil)
