amd: Add user queue HQD count to hw_ip info

Browse Source 
Add a new field userq_num_hqds to drm_amdgpu_info_hw_ip to expose the
number of available hardware queue descriptors (HQDs) for user queues.
This allows userspace to query the maximum number of user queues that
can be created for a particular IP block.

v2: we should also put userq_num_hqds into radeon_info and
print it where other fields are printed. (Marek Olšák)

v3: rename num_userqs to num_queue_slots
    and add print log in ac_print_gpu_info. (Marek Olšák)
v4: rename userq_num_hqds to userq_num_slots in hw_ip_info,
    and update the hw information (Marek Olšák)
