Vincent Palatin 49bfe43b90 usb: fix sysjump
Ensure that we can re-etablish a proper USB communication after a
sysjump by properly disabling the USB stack before jumping.
So the host sees a USB disconnection and can properly re-initialize the
device when it re-appears.

BRANCH=samus
BUG=none
TEST=On Twinkie, use the "sysjump RW" command on the USB console
and see the prompt coming back after a few seconds.
