In order to make single zImage work for ARM architecture,
we need to make sure we don't depend on private headers.

Move USB platform_data to <linux/platform_data/omap-usb.h>
and keep only internal functions in <plat/usb.h>.

The new standard seems to be subsystem-soc.h, so usb-omap.h :)

> and keep only internal functions in <plat/usb.h>.

Can the remaining parts be in #include "usb.h" in mach-omap2?

Tony
