USB OTG: Add generic driver for ULPI OTG transceiver

This adds a minimal generic driver for ULPI connected transceivers,
using the OTG framework functions recently introduced.

The driver got a table to match the ULPI chips, which currently only has
one entry for NXP's ISP 1504 transceiver.

           This driver can also be built as a module.  If so, the module
           will be called isp1301_omap.
