drm/radeon/kms: add dpm support for rv7xx (v4)

This adds dpm support for rv7xx 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: reduce stack usage v3: fix 64 bit div v4: fix state enable Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
