drm/amdgpu/sdma7.1: add support for disable_kq
Plumb in support for disabling kernel queues and make it
the default. For testing, kernel queues can be re-enabled
by setting amdgpu.user_queue=0. Kernel queues are still
created for use by the kernel driver for memory management,
etc., just not user submissions.
