Subject: [PATCH v1 1/2] regulator: dt-bindings: Add TI TPS65214 PMIC bindings

- TPS65214 is a Power Management IC with 3 Buck regulators and 2 LDOs.
- TPS65214 has 2 LDOS and 1 GPO, whereas TPS65219 has 4 LDOs and 2 GPOs.
- TPS65214's LDO1 maps to TPS65219's LDO3.
- A key difference between TPS65215 & TPS65214 are the LDO current and
  voltage output ranges and the configurable options available.
- The remaining features for both devices are the same.
