[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).
