uio_usbdebug: User-space-i/o framework for usbdebug

uio_usbdebug enables you to debug coreboot's usbdebug driver inside a
running operating system (only Linux at this time). This comes very
handy if you're hacking the usbdebug driver and don't have any other
debug output from coreboot itself.

Currently, only Intel chipsets are supported.
