drm/amdgpu: add initial support for UMSCH
Add basic data structure, dummy ring functions
and ip functions for UMSCH.
Implement sw_init(ring_init and init_microcodede) and
hw_init(load_microcode), UMSCH can boot up now.
Implement hw_init(ring_start) and hw_fini(ring_stop),
UMSCH is ready for command submission now.
Implement set_hw_resources and add/remove_queue,
UMSCH is ready for scheduling now.
Aggregated doorbell is used to notify UMSCH FW that
there is unmapped queue with corresponding priority level
(e.g., AGDB[0] for Real time band, etc.) is updating its job.
v2: squash together initial patches to avoid breaking the
build (Alex)
