[ARM] 5611/1: ep93xx: update ts72xx nor flash support
Update the NOR flash support for TS-7200. The TS-7200 models all have 16-bit NOR flash. Update the platform init to support this. Remove the private TS72XX_NOR_* defines and use the common ep93xx defines for the external chip select physical base address instead. Move the NOR flash registration into a static __init function. When the NAND flash support is updated this function will also be used to register the NAND flash for the TS-7250 and TS-7260.
