[PATCH] update UBI support

[Sascha Hauer]

This adds the UBI layer from Linux-3.10. Since the changes in the
UBI layer are huge I chose to remove the old UBI support first and
do a fresh start. This brings us fastmap support which for the
first time makes UBI a performant alternative to using the NAND
flash naked.
