Omap3 platform support added at the same level as davinci.
The interface for usbtty to use the musb device support was added.
Verified on omap3 beagle, zoom1 and zoom2.

#ifndef CONFIG_OMAP3_EVM

I will include this in the next revision. Will the omap3_evm need to add its own PHY initialization code ?
