drivers: regulator: pca9420: refactor voltage range handling
Voltage ranges were hardcoded in Devicetree, however, things can be significantly simplified by using the recently introduce linear ranges API. All values are now computed using information stored in the driver, so there is no need to store any lookup table in ROM. Code should now both be faster in average and consume less ROM.
