Nowadays MTD supports an MTD_OOB_AUTO option which allows users
to access free bytes in NAND's OOB as a contiguous buffer, although
it may be highly discontinuous.
This patch teaches JFFS2 to use this nice feature instead of the
old MTD_OOB_PLACE option. This for example caused problems with
OneNAND. Now JFFS2 does not care how are the free bytes situated.
This may change position of the clean marker on some flashes,
but this is not a problem. JFFS2 will just re-erase the empty
eraseblocks and write the new (correct) clean marker.

Remove unused and broken mtd->ecctype and mtd->eccsize fields
from struct mtd_info. Do not remove them from userspace API
data structures (don't want to breake userspace) but mark them
as obsolete by a comment. Any userspace program which uses them
should be half-broken anyway, so this is more about saving
data structure size.

Remove ugly and weird MTD_PROGREGION_CTRLMODE_VALID() and
MTD_PROGREGION_CTRLMODE_INVALID() macros. There is only one

Anyway, this patch is a preparation for removing mtd->ecctype

OneNAND has internal bufferRAMs. The driver keeps track of
what is in the bufferRAM to save having to load from the
NAND core. After an erase operation, the driver must

Add checks to ensure that out-of-band reads and writes are
not attempted with an invalid offset or length. Specifically,
the offset must be less than the size of oob for a page
and the length must not go beyond the size of the device.
Additionally the checks must adjust for auto-placement
(MTD_OOB_AUTO) of oob data.

In commit c172471b78255a5cf6d05383d9ebbf0c6683167a Nico switched to using
common code for polling for command completion. Unfortunately he also used
a common default timeout for both write and erase commands, despite the
fact that erases can take a _whole_ lot longer. Use a more sensible
default for erase timeout.

OneNAND double-density package (DDP) has two chips, each with
their own bufferRAM. The driver will skip loading data from
the NAND core if the data can be found in a bufferRAM, however
in that case, the correct chip's bufferRAM must be selected
before reading from bufferRAM.

It use blockpage instead of a pair (block, page). It can also cover a small chunk access. 0x00, 0x20, 0x40 and so on.
And in JFFS2 behavior, sometimes it reads two pages alternatively.
e.g., It first reads A page, B page and A page.
So we check another bufferram to find requested page.

the data written is read back and compared. The comparison
was being made between dataRAM buffers, but this does not
verify that the data made it to the dataRAM correctly in
