NAND: Update 4xx NDFC driver to match updated nand subsystem This patch changes the 4xx NAND driver ndfc.c to match the new infrastructure from the updated NAND subsystem. This NAND subsystem was recently synced again with the Linux 2.6.22 MTD/NAND subsystem. Tested successfully on AMCC Sequoia and Bamboo. Signed-off-by: Stefan Roese <sr@denx.de>
