No, you definitely shouldn't be doing this - the regulator names should
reflect the names the device has in the datasheet to aid people in going
from software to the hardware and back again.  They shouldn't be
dynamically generated at runtime.  If you need to namespace by device
provide an interface which explicitly namespaces by device rather than
hacking it into another interface, the usual thing is to use the struct
device as the context.
