Attach the PNOR mtd device to UBI
Create a new service that gets the PNOR mtd device
from /proc/mtd and performs a ubiattach to it.
Since only one mtd device (PNOR) is being attached,
it's assumed that a /dev/ubi0 device is created.
Later when more devices/chips are attached, a udev
rule might be needed to link them to a specific ubi
device number.
