regulator: tps65219: Add TI TPS65214 Regulator Support
Add support for TPS65214 regulators (bucks and LDOs) to the TPS65219 Regulator Driver as the TPS65214/TPS65214/TPS65219 PMIC devices have significant register map overlap. TPS65214 is a Power Management IC with 3 Buck regulators (like TPS65215/TPS65219) and has 2 LDOs (like TPS65215).
