Hi all,
Here are some FS USB platform init changes to allow further improvment
of the code for muxing, register access and hwmod.
This set mostly moves the code around to split it between mach-omap1
and mach-omap2.
Regards,
Tony

We want to split old FS USB platform init code and stop doing pin multiplexing
under plat-omap. First move 24xx specific init code into omap2_usb[012]_init
functions.

Move omap2 FS USB platform init code into mach-omap2/usb-fs.c. This will
allow further work later on to use omap hwmod for initializing the
device.
