USB: transceiver changes for 3.4

Here we have a big rework done by Heikki Krogerus (thanks) which
splits OTG functionality away from transceivers.

We have known for quite a long time that struct otg_transceiver was
a bad name for the structure, considering transceiver is far from
being OTG-specific (see 4e67185).
