Thanks for your patch Andrew

In order for the MCU domain to access this PMIC and its children in
u-boot SPL, the nodes need to be marked appropriately otherwise they
are not seen by SPL.
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.

Add bootph in on regulator node should be enough,
As I see SPL/u-boot does not need all nodes.
FYI,
