ARM: OMAP1: Make omap1 boards to use omap_nand_platform_data
This patch adds omap_nand_platform data based on a patch by Shahrom Sharif-Kashani <sshahrom@micron.com>, and makes omap1 boards to use omap_nand_platform_data instead of nand_platform_data used earlier. Signed-off-by: Tony Lindgren <tony@atomide.com>
