And that's really true?  I ask since I recall there's some SoCs where
it's a lot more theoretical than practical to have a PMIC other than the
one the EVM uses.  But, yes, board level imply is the way to go then.
The rule of thumb should be that if it's not really optional, the board
or SoC should imply it if there's a reason to not have it, or select it
if it's required.
