We model common mode voltage inputs as a regulator consumer (e.g. vcm-supply in
DT), so should we make this a regulator provider instead?
It could be used with "regulator-output" to be able to control it from sysfs
or if the amplifier ends up in the devicetree for other reasons, the amplifier
driver could control the regulator instead of requiring it to by done in sysfs.
