No, I think MFD + scan handler inside the MFD driver is the way to go.
We don't want to trash ACPI core with stuff that does not belong there

Also you don't need to modify acpi_default_enumeration() because you can
mark your device enumerated in the MFD driver. So all the dirty details
will be in the MFD driver and not in ACPI core.
