ARM: omap1: move mach/usb.h to include/linux/soc

The register definitions in this header are used in at least four
different places, with little hope of completely cleaning that up.

Split up the file into a portion that becomes a linux-wide header
under include/linux/soc/ti/, and the parts that are actually only
needed by board files.
