drm/amdgpu: Enable HDP memory light sleep
Due to the register name and setting change of HDP memory light sleep on Vega20,change accordingly in the driver. Signed-off-by: Kenneth Feng <kenneth.feng@amd.com> Reviewed-by: Evan Quan <evan.quan@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
