From: Boyuan Zhang <boyuan.zh...@amd.com>
For smu ip with multiple vcn instances (smu 11/13/14), remove all the
for loop in dpm_set_vcn_enable() functions. And use the instance
argument to power up/down vcn for the given instance only, instead
of powering up/down for all vcn instances.
v2: remove all duplicated functions in v1.
remove for-loop from each ip, and temporarily move to dpm_set_vcn_enable,
in order to keep the exact same logic as before, until further separation
in the next patch.
