arm64: dts: ti: k3-am69-sk: Mark tps659413 regulators as bootph-all
In order for the MCU domain to access this PMIC, a regulator needs to be marked appropriately otherwise it is not seen by SPL and therefore not configured. This is necessary if the MCU domain is to program the TPS6594 MCU ESM state machine, which is required to wire up the watchdog in a manner that will reset the board.
