There is actually a third PMIC in this family RC5T619 which has 5, that
is where the number comes from. But that PMIC also has 12 LDO's so the
numbers are a bit a mix and much right now...

If I have to amend something anyway, I will fix that. Otherwise I look
at it as a preparation for the one which adds RC5T619 support :-)
