drm/amdgpu: extend AMDGPU_CTX_PRIORITY_NORMAL comment

Browse source 
Currently the AMDGPU_CTX_PRIORITY_* defines are used in both
drm_amdgpu_ctx_in::priority and drm_amdgpu_sched_in::priority.

Extend the comment to mention the CAP_SYS_NICE or DRM_MASTER requirement
is only applicable with the former.
