ARM: OMAP2+: nand: unify init functions
Helper function for updating nand platform data has been added the capability to take timing structure arguement. Usage of omap_nand_flash_init() has been replaced by modifed one, omap_nand_flash_init was doing things similar to board_nand_init except that NAND CS# were being acquired based on bootloader setting. As CS# is hardwired for a given board, acquiring gpmc CS# has been removed, and updated with the value on board. NAND CS# used in beagle board & omap3evm was found to be CS0. Thomas Weber <thomas.weber.linux@googlemail.com> reported that value of devkit8000 to be CS0. Overo board was found to be using CS0 based on u-boot, while google grep says omap3touchbook too has CS0.
