arm64: dts: ti: k3-am62a7-sk: Add support for TPS6593 PMIC 



This patch adds support for TPS6593 PMIC on main 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.
