regulator: If a single voltage is set with device tree then set apply_uV
Otherwise there is no way in the bindings to configure a fixed voltage via software. It seems reasonable to assume that if the binding explicitly specifies a voltage we want to actually use that voltage. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
