arm64: dts: ti: k3-j721e-sk: Add TPS6594 family PMICs 



This patch adds support for TPS6594 PMIC family on wakeup I2C0 bus.
These devices provide 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.
