I was seeing a bunch of LDO initialization's fail while bringing up an
upcoming SoC/Board which uses these same set of PMIC's, some of those
are fixed with this patch, but I still have a couple more failing due
to the voltage that I try to init them to being out of range based on
their voltage range, can you pls check if those are of the right type?

The ones now failing are, ldo12 from pm8550 and smps4 from pm8550ve.
