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.

For hardware blocks whose performance counters are accessed via MMIO
registers, KFD provides the support for those privileged blocks.

IOMMU is one of those privileged blocks. Most performance counter properties
required by Thunk are available at /sys/bus/event_source/devices/amd_iommu.

This patch adds properties to topology in KFD sysfs for information not
available in /sys/bus/event_source/devices/amd_iommu. They are shown at
/sys/devices/virtual/kfd/kfd/topology/nodes/0/perf/iommu/ formatted as
/sys/devices/virtual/kfd/kfd/topology/nodes/0/perf/<block>/<property>, i.e.
/sys/devices/virtual/kfd/kfd/topology/nodes/0/perf/iommu/max_concurrent.

Currently, the KFD topology information is generated by parsing the CRAT
(ACPI) table. However, at present CRAT table is available only for AMD
APUs. To support CPUs on systems without a CRAT table, the KFD driver will
create a Virtual CRAT (VCRAT) table and then the existing code will parse
that table to generate topology.
