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.

+          If you say yes here you get support for the Philips ISP1301
+          USB-On-The-Go transceiver working with the OMAP OTG controller.
+          The ISP1301 is a full speed USB  transceiver which is used in
+          products including H2, H3, and H4 development boards for Texas
+          Instruments OMAP processors.
+
+          This driver can also be built as a module.  If so, the module
+          will be called isp1301_omap.
