Let's make the raw NAND API consistent by patching all helpers to
take a nand_chip object instead of an mtd_info one.
Now is nand_release()'s turn.

Applied the patchset after addressing Miquel's comments.

Actually, I'm not sure I understand that comment, but I guess it's
talking about races between read/write and erase paths, so nothing
related to the changed I'm doing here.

->addr_fail and ->addr fields into account after part_erase() has
returned.
While we're at it, get rid of the erase_info->mtd field which was only
needed to let mtd_erase_callback() get the partition device back.

mtd_erase() can return an error before ->fail_addr is initialized to
MTD_FAIL_ADDR_UNKNOWN. Move this initialization at the very beginning

None of the mtd->_erase() implementations work in an asynchronous manner,
so let's simplify MTD users that call mtd_erase(). All they need to do
is check the value returned by mtd_erase() and assume that != 0 means
failure.

Some fields are not used by MTD drivers, users or core code. Moreover,
those fields are not documented, so get rid of them to avoid any
confusion.
