[PATCH 03/29] drm/amd/pm: add inst to smu_dpm_set_vcn_enable

From: Boyuan Zhang <boyuan.zhang at amd.com>
First, add an instance parameter to smu_dpm_set_vcn_enable() function,
and calling dpm_set_vcn_enable() with this given instance.
Second, modify vcn_gated to be an array, to track the gating status
for each vcn instance separately.
With these 2 changes, smu_dpm_set_vcn_enable() will check and set the
gating status for the given vcn instance ONLY.
v2: remove duplicated functions.
remove for-loop in dpm_set_vcn_enable(), and temporarily move it to
to smu_dpm_set_power_gate(), in order to keep the exact same logic as
before, until further separation in next patch.
v3: add instance number in error message.
