The current code only allows to automatically set
root device on MTD partitions. Move the code to MTD
core to allow to use it with all MTD devices.

ar71xx: Add new subtarget nand for WNDR4300

Add new subtarget nand with UBI/UBIFS including GLUEBI and squashfs.
This target will be used for NAND based router which make use of
UBI (and maybe UBIFS later on) in order to provide proper NAND
support.
