drm/radeon/kms: add dpm support for evergreen (v4)
This adds dpm support for evergreen asics. This includes: - clockgating - dynamic engine clock scaling - dynamic memory clock scaling - dynamic voltage scaling - dynamic pcie gen1/gen2 switching (requires additional acpi support) Set radeon.dpm=1 to enable. v2: reduce stack usage, rename ulv struct v3: fix thermal interrupt check notices by Jerome v4: fix state enable Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
