From: Jerome Neanne <jneanne@baylibre.com>

This patch adds support for TPS65933A PMIC on wkup I2C0 bus.
This device provides regulators (bucks and LDOs), but also
GPIOs, a RTC, a watchdog, an ESM (Error Signal Monitor)
which monitors the SoC error output signal, and a PFSM
(Pre-configurable Finite State Machine) which manages the
operational modes of the PMIC.
