d07a97e939 drm/nouveau/volt/gk104: round up in gk104_volt_set 
We always want a equal or higher voltage than the requested ones, otherwise
nouveau undervolts.

1531dbbb56 drm/nouveau/volt/gk104: add support for pwm and gpio modes 
Most Keplers actually use the GPIO-based voltage management instead of the new
PWM-based one. Use the GPIO mode as a fallback as it already gracefully handles
the case where no GPIOs exist.

All the Maxwells seem to use the PWM method though.

v2:
 - Do not forget to commit the PWM configuration change!
