Chances are these are not fixed regulators.. Typically the these
come from external regulators controlled by GPIO pins. Sounds
like you have the schematics so it would be best to verify it.
If they come from something not yet supported, let's at least
document it with comments.
Also looks like all the am43xx boards are using vmmcsd_fixed,
might be worth checking those as well while at it.
Regards,
Tony
