[PATCH] MTD: OMAP2-NAND: Fix partition reading from board info

Last time I explicitly tried was back on OMAP1.  I then dug into doc's it was said that the bit was hardwired at the integration point.  I don't recall signal name.

Now, Peeking into OMAP2 (armv6) MPU integration docs I see that BIGENDINIT is pulled low.  This forces the behavior as I indicated.  OMAP3 (armv7) does something similar at cpu-to-bus bridge.

Doing a quick desktop search in documents I see the armv6 behavior is defined as part of BIGENDINIT in ARM TRMs.  I'll guess SETEND instruction follows what ever that dictates.  I don't know as I've never tried.
