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.
