The level is used by everything related to GENPD, while voltage is used
by the domain driver.

I think it's cleaner to separate the level from voltage, even though
they are set to the same values, which is done purely for convenience.
The 0,1,2,3 levels are meaningless in the context of this power domain,
while voltages make total sense.
