[PATCH v4 1/2] arm64: dts: ti: k3-j784s4-evm: Mark tps659413 regulators as bootph-all

From: Andrew Halaney <ahalaney at redhat.com>

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.
