more descriptive names instead of quite ambiguous "asn".

The main problem here is usb gadget subsystem, which simply doesn't support
deferred probe yet. UDC driver (which uses those regulators) need to be
initialized before usb gadget driver (i.e. mass storage or c

This reverts commit 10bcdfb8ba24760f715f0a700c3812747ef5. There is
no consensus on the bindings for the reserved memory, so the code for
handing it will be reverted.
