drm/radeon/kms/pm: Disable voltage adjust on RS780/RS880
The vddc value in the power tables is not an actual voltage like on discrete r6xx/r7xx/evergreen systems, but instead has a symbolic meaning (e.g., NONE, LOW, HIGH, etc.). See atombios.h Most RS780/RS880 vbioses don't have a SetVoltage table anyway, so it shouldn't be doing anything to the hardware at the moment. I need to figure out how voltage is supposed to work on the newer IGPs; until then, disable it. Signed-off-by: Alex Deucher <alexdeucher@gmail.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
