This patch gets usbdebug console working in romstage.

- actually hook up usbdebug in printk/print_ for romstage
- make usbdebug.c more similar to the Linux kernel version it was
  originally derived from.
- increase retries and timing for usbdebug init (at least one chipset
  seems to need this)
- src/pc80/usbdebug_serial.c is not needed
- some small console cleanups
