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).

          TPS65219 series of PMICs have 3 single phase BUCKs & 4 LDOs
          voltage regulators.
          TPS65215 PMIC has 3 single phase BUCKs & 2 LDOs.
-         Both PMICs support software based voltage control for different voltage domains.

+         LDOs. One LDO supports a maximum output current of 300 mA and the
+         other a maximum of 500 mA
