KIQ is queue-memory based initialization method: setup KIQ queue
firstly, then send command to KIQ to setup other queues, without
accessing registers.
For virtualization, need KIQ to access virtual function registers
when running on guest mode.
V2: use amdgpu_bo_create/free_kernel to allocate BO.

Change History
--------------
v4: Changes suggested by Emil, Christian
- return -ENODATA for asics with unlimited sessions
v3: changes suggested by Christian
- Add a check for UVD IP block using AMDGPU_HW_IP_UVD
query type.
- Add a check for asic_type to be less than
CHIP_POLARIS10 since starting Polaris, we support
unlimited UVD instances.
- Add kerneldoc style comment for
amdgpu_uvd_used_handles().
v2: as suggested by Christian
- Add a new query AMDGPU_INFO_NUM_HANDLES
- Create a helper function to return the number
of currently used UVD handles.
- Modify the logic to count the number of used
UVD handles since handles can be freed in
non-linear fashion.
v1:
- User might want to query the maximum number of UVD
instances supported by firmware. In addition to that,
if there are multiple applications using UVD handles
at the same time, he might also want to query the
currently used number of handles.
For this we add two variables max_handles and
used_handles inside drm_amdgpu_info_hw_ip. So now
an application (or libdrm) can use AMDGPU_INFO IOCTL
with AMDGPU_INFO_HW_IP_INFO query type to get these
values.

drm_debugfs_cleanup() now removes all minor->debugfs_list entries
automatically, so the drm_driver.debugfs_cleanup callback is not
needed. Also remove the unused tilcdc_module_ops.debugfs_cleanup()
callback. drm_debugfs_cleanup() removes all debugfs files using
debugfs_remove_recursive(), so there should be no need for such a
callback in the future.
