The platform data can now specify which external memory banks to probe for NAND chips, and in which order. Banks that contain a NAND are used and the other banks are freed. Squashed version of development done in jz-2.6.38 branch. Original patch by Lars-Peter Clausen with some bug fixes from me. Thanks to Paul Cercueil for the initial autodetection patch.
