This adds support for OTG transceivers directly connected to the ULPI
interface. In particular, the following details are added
- a struct for low level io functions (read/write)
- a priv field to be used as 'viewport' by low level access functions
- an (*init) and (*shutdown) callbacks, along with static inline helpers
- a (*set_vbus) callback to switch the port power on and off
- a flags field for per-transceiver settings
- some defines for the flags bitmask to configure platform specific
details

Why not just use the standard ULPI control register bit defintitions
instead of these?
