drm/radeon/kms/ni: load default sclk/mclk/vddc at pm init
The vbios only partially initializes the memory controller on NI, so now we need to load the MC ucode in the driver and set the default clocks once the ucode is loaded. Signed-off-by: Alex Deucher <alexdeucher@gmail.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
