mfd: tps65219: Add driver for TI TPS65219 PMIC

The TPS65219 is a power management IC PMIC designed to supply a wide
range of SoCs in both portable and stationary applications. Any SoC can
control TPS65219 over a standard I2C interface.

It contains the following components:
- Regulators.
- Over Temperature warning and Shut down.
- GPIOs
- Multi Function Pins (MFP)
- power-button

This patch adds support for tps65219 PMIC. At this time only
the functionalities listed below are made available:

- Regulators probe and functionalities
- warm and cold reset support
- SW shutdown support
- Regulator warnings via IRQs
- Power-button via IRQ
