Subject: MFp4: //depot/projects/usb@155834
Factor out roothub process into the USB bus structure for
all USB controller drivers. Essentially I am trying to
save some processes on the root HUB and get away
from the config thread pradigm. There will be a follow up
commit where the root HUB control and interrupt callback
will be moved over to run from the roothub process.
Total win: 3 processes become 1 for every USB controller.
