vexpress64: juno: add default NOR flash boot
This modifies the vexpress64 Juno configuration so that
it will by default load and boot a kernel and a device tree
from the images stored in the NOR flash. When we are
at it, also define the proper command line for the Juno and
indicate that the USB stick (/dev/sda1) is the default
root file system.
