I don't understand why we need this flag. Shouldn't we just be making
the reference counts for the supplies correct and then have the
regulator disabled in the late initcall as a result of its refcount
falling to zero when the children are disabled? I think what we need to
do here is always take a reference to the supply if the child is enabled
during boot, then in the initcall we can just disable the parent
regulator as normal.
