[U-Boot] USB device support for OMAP3

[Tom]

The recently posted patches enable usb device support for omap3
They are against the repository  http://git.denx.de/u-boot-arm.git, 
branch 'next'

You can also view them in my development tree
http://dev.omapzoom.org/?p=trix/u-boot.git;a=shortlog;h=refs/heads/arm-next-development
starting at commit 50031bc80615f4fcafcdc613020b87a326aaed92

The device support was usbtty.
This was run tested on beagle, zoom1 and zoom2.
The maintainer of the beagle and zoom1 boards should decide if they want 
a usb device
starting for their board.
For zoom2, the usbtty is the console when the debug board is not present.

There were some small changes to the musb common code.
The devinci maintainer should check that their host support is ok.

There is a large change to usb structures that should be also tested out.
I ran this through MAKEALL arm, mips and ppc but I do not have a board 
that uses
usb in host mode.  

After this I plan on submitting a new usb device called 'fastboot'
It provides a limited set of basic commands to help develop over just usb.
Here is a link.
