This patch adds (write|read)_buf callbacks to plat_nand.

The NAND on the TS-7800 provisioned by the FPGA allows readw() and
readl() to be used which gives a 2.5x speed up.  To be able to use this
from the plat_nand driver a hook for read_buf (and also write_buf whilst
we are in there) need to be made available.  This patch adds the hook.

Remove some legacy code from the davinci_nand driver, which made
cmdlinepart ignore the the MTD ID passed to it.  Boards can have
multiple NAND chips, and some do (like the DM357 EVM), so this
dated hack is undesirable.

Correct labels are like "davinci_nand.0" (for chipselect 0).

Minimal support for the 4-bit ECC engine found on DM355, DM365,
DA830/OMAP-L137, and similar recent DaVinci-family chips.

This is limited to small-page flash for now; there are some page
layout issues for large page chips.  Note that most boards using
this engine (like the DM355 EVM) include 2GiB large page chips.

Sanity tested on DM355 EVM after swapping the socketed NAND for

Make the DaVinci NAND driver require platform_data with
board-specific configuration.  We can't actually do any
kind of sane job of configuring it otherwise.

Also fix the comment about picking the "best" ECC mode.

We can't do those any more; that relied on knowing what kind
of CPU we're using (they don't all support 4-bit ECC), and
current policy is that drivers not have cpu_is_*() checks.
