arm64: dts: ti: k3-j7200-som-p0: Add TP6594 family PMICs
This patch adds support for TPS6594 PMIC family on wakup I2C0 bus.
Theses devices 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.
