MTD driver cleanups...

 - Fix AFS partitioning oops when no partitions are found
 - Add missing spin_unlock, optimise buffer writes in Intel NOR driver
 - Fix DiskOnChip Millennium Plus register OutputControl register definition
 - Fix DiskOnChip drivers to indicate correct ECC type
 - Fix map drivers to use ARRAY_SIZE instead of redefining it.
 - Make uCLinux map driver depend on !MMU
 - Fix NAND write verify problem on some chips
 - Other trivia from Rusty.
