drm/radeon: add dpm support for CI dGPUs (v2)
This adds dpm support for btc asics. This includes: - dynamic engine clock scaling - dynamic memory clock scaling - dynamic voltage scaling - dynamic pcie gen switching Set radeon.dpm=1 to enable. v2: remove unused radeon_atombios.c changes, make missing smc ucode non-fatal Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
