[ARM] pxa/zaurus: fix NAND flash OOB layout for Borzoi

Borzoi, Terrier and Akita use the same NAND Flash OOB layout, which
seems to be different from Spitz for some reason. Here is a fix.

When the code was ported to the platform data, the map was applied just
for Akita.

After this patch, Flash works again on Borzoi. Terrier still has a
problem with partition table different from Borzoi (unfixable without
reading of the system configuration in flash) and JFFS2 partitions can
be mounted (with some "Empty flash at ... ends at ..." in the syslog).
