drm/amd/pm: only send GmiPwrDnControl msg on master die (v3)
PMFW only returns 0 on master die and sends NACK back on other dies for the message. v2: only send GmiPwrDnControl msg on master die instead of all dies. v3: remove the pointer check for get_socket_id and get_die_id as they should be present on Aldebaran.
