[RFC 4/5] regulator: tps65090: Set voltage for fixed regulators

[Javier Martinez Canillas]

According to the tps65090 data manual [0], the DCDC1 and DCDC2
step-down converters and the LDO's have a fixed output voltage.

Add this information to the driver since these fixed regulators
be used as input supply for load switches which don't provide
an output voltage and their parent supply voltage is used.
