Could you check, once, which nodes regulator/ldo, are really needed in
u-boot stage.

Unless default power-on settings of PMIC is not working for this board
or you want to program something during SPL stage like AVS or so, then
only add boot-ph else you can consider to skip pmic at u-boot SPL stage.
