actually, this is a workaround to the fact that we're not creating all
platform_devices in arch/arm/mach-omap2/ :-)

If we had the musb allocation there, we could easily handle
usb_bind_phy()

right, but generic phy framework can handle everything just fine, the
only problem is that names are changing.
