Harish Kasiviswanathan 6b855f7b83 drm/amdkfd: Check against device cgroup 
Participate in device cgroup. All kfd devices are exposed via /dev/kfd.
So use /dev/dri/renderN node.

Before exposing the device to a task check if it has permission to
access it. If the task (based on its cgroup) can access /dev/dri/renderN
then expose the device via kfd node.

If the task cannot access /dev/dri/renderN then process device data
(pdd) is not created. This will ensure that task cannot use the device.

In sysfs topology, all device nodes are visible irrespective of the task
cgroup. The sysfs node directories are created at driver load time and
cannot be changed dynamically. However, access to information inside
nodes is controlled based on the task's cgroup permissions.
