This is a fresh UBI import from Linux v3.10
This is done mainly to get fastmap support.
This was tested with the i.MX nand driver, the MXS nand driver and
on CFI NOR flash.

To update to the latest UBI support from the Kernel first remove
the old UBI support. Without it the update will be even less reviewable.

CFI Flash is currently handled outside the mtd layer which makes it
a special case. Integrate it into mtd so that we get rid of this
special status.

To get rid of:
(MTD_OOB_DEVICE && MTD_RAW_DEVICE) selects NAND_READ_OOB which has unmet direct dependencies (MTD && NAND)

Add the MSystem disk-on-chip G3 support, taken from the
linux kernel with few amendments to bring it into barebox.

Add a device to read and write to MTD data and oob
(/dev/mtdraw<N>).
The device is constrained in a separate source file, so that
further improvement of commands (such as nandwrite) could
make it useless, and easy to remove.

Change NAND_WRITE into MTD_WRITE.
Change "page_shift" references in the core, which are purely
NAND, into mtd->writesize which is MTD generic.
Rename all "info" (struct mtd_info) into "mtd".
Also provide a parameter to add_mtd_device() so that legacy
nand devices still appear as nand<N>.
