[PATCH] mtd: nand: support BENAND (Built-in ECC NAND)

> Are you planning to add support to other Toshiba BENAND ?

Unfortunately, I am not currently, because I do not have 
any boards of the other BENANDs.

But I suppose that it is easy to support the other BENANDs 
by little modification of nand_read_page_benand() to get 
a number of bitflips.
