[PATCH 01/18] drm/amd/pm: add new vcn enable function pointer

From: Boyuan Zhang <boyuan.zhang at amd.com>

The new function dpm_set_vcn_enable_instance() will be used to enable
or disable vcn engine dynamic power for the given vcn instance.

The original function dpm_set_vcn_enable() will still be used to enable
or disable vcn engine dynamic power for all vcn instances as before.
