arm64: dts: ti: k3-am69-sk: Add support for TPS6594 PMIC

Browse Source 
This patch adds support for TPS6594 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.
