Presently, IP level callback is not required for per instance as this
only used in VCN. This can be kept internal now.
Suggest to squash the changes in 12-15 as
1) Add below to amdgpu_vcn_inst.
int (*set_powergating_state)(struct amdgpu_vcn_inst* vcn_inst, enum
amd_powergating_state state)
2) Assign the respective IP specific fucntion pointer and call like
vcn_inst->set_powergating_state(vcn_inst, state); when required.
Thanks,
