colibri_t20: nand: integrate NVIDIA partition table parsing
NVIDIA's NAND layout includes a partition table that can be used to
generically construct the mtdparts kernel boot argument. As an added
benefit this is completely independent of the underlying NAND part
used which differs with various module versions. It further allows our
customer easy adoption to their own custom partition layout.
Initial partition table parsing courtesy of Mitja Špes from LXNAV.
