USB: move isp1301_omap to drivers/usb/otg

This moves the isp1301-omap driver from the drivers/i2c/chips
directory (which will be shrinking) into a new drivers/usb/otg
directory (which will grow, with more drivers and utilities).

Note that OTG infrastructure needs to be initialized before
either host or peripheral side USB support, and may be needed
before for pure host or pure peripheral configurations.
