drm/amdgpu: add new HDP CG flags
HDP 5.0 supports SRAM power gating. all the LS (Light Sleep)/ DS (Deep Sleep)/SD (Shut Down) modes are supported. However, only one of these modes can be enabled at one time. There is no dynamic power mode switch support. clock/power gating has to be disabled before making any power mode change.
