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).

-	  This driver supports TPS65219 series and TPS65215 voltage regulator chips.
+	  This driver supports TPS65219, TPS65215, and TPS65214 voltage
+	  regulator chips.
 	  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.
+	  TPS65214 PMIC has 3 synchronous stepdown DC-DC converters & 2
+	  LDOs. One LDO supports a maximum output current of 300 mA and the
+	  other a maximum of 500 mA
+	  All 3 PMICs support software based voltage control for different
+	  voltage domains.
