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.
