drm/amdgpu/userq: rework driver parameter
Replace disable_kq parameter with user_queue parameter.
The parameter has the following logic:
-1 = auto (ASIC specific default)
0 = user queues disabled
1 = user queues enabled and kernel queues enabled (if supported)
2 = user queues enabled and kernel queues disabled
The default behavior (-1) is currently the same as 0 for current
ASICs. To enable user queues (in addition to kernel queues) set
user_queue=1. To enable user queues and disable kernel queues
(to make all resources available to user queues), set user_queue=2.
