Matt DeVillier 1bd93d6679 Eliminate use of CONFIG_USB_BOOT_DEV ... mount-usb switched to dynamic USB device detection a while back, so eliminate instances of CONFIG_BOOT_USB_DEV, and derive the mounted USB device from /etc/mtab in the one place where it's actually needed (usb-scan). Clean up areas around calls to mount-usb for clarity/readability.
