As the FS USB code is not being actively used for omap2+ there's no point keeping it around for omap2+. Let's make the FS USB platform init code omap1 only so we can remove the last user of omap_read/write for omap2+, and simplify things for further USB, DMA, and device tree related work. While at it, also group the mach includes for the related drivers.
