drm/amd/display: Log DMCUB trace buffer events
[Why]
We want to log DMCUB trace buffer events as Linux kernel traces.
[How]
Register an IRQ handler for DMCUB outbox0 interrupt in amdgpu_dm,
and log the messages in the DMCUB tracebuffer to a new DMCUB
TRACE_EVENT as soon as we receive the outbox0 IRQ from DMCUB FW.
