This adds dpm support for rv6xx asics. This includes: - clockgating - dynamic engine clock scaling - dynamic memory clock scaling - dynamic voltage scaling - dynamic pcie gen1/gen2 switching Set radeon.dpm=1 to enable. v2: remove duplicate line v3: fix thermal interrupt check noticed by Jerome Signed-off-by: Alex Deucher <alexander.deucher@amd.com> Reviewed-by: Christian König <christian.koenig@amd.com>
