Claim the MPP pins for the NAND flash controller only when it's actually

I haven't wrapped this with a configuration option because I think it
should be safe to enable by default. It will either re-apply the same
MPP configuration that has already been done in the board init or put
the MPP pins into the correct mode to access NAND.
I've only got access to one kirkwood based board with NAND flash so I'd
appreciate some feedback from someone with access to a few different
boards.
From the datasheets I have access to it looks like there is only one
possible MPP configuration for NF_IO[0-7] so that is what I've
implemented. I'm not aware of anything using this driver that needs a
different MPP config.
Changes in v2:
- make nand_config static const
Scott, are you okay with this patch in v2? If yes, will you pull it?
Or should I include it in a marvell pull request?
Thanks,
Stefan
