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.
