The queue scheduler divides into two sections, one section is process bounded
and the other section is device bounded.
The process bounded section is handled by this module. The PQM handles usermode
queue setup, updates and tear-down.

v3:

Used kernel parameter to limit queues per process instead of define
Added use of doorbell address from user

v4:

Modified pqm_create_queue so that only when creating usermode queues the
driver should return the queue properties to the userspace.

Added an info message print when no more queues can be opened because of the
queue per process limitation

v5:

Move amdkfd from drm/radeon/ to drm/amd/
Various fixes
