Currently aemif is supported in two places separately. By the platform driver in drivers/memory and by a hand crafted driver in mach-davinci. We want to drop the latter but also keep the legacy mode. Add support for board files to the aemif driver. The new structure in platform data currently only contains the chip select number, since currently existing users don't require anything else, but it can be extended in the future. While extending the platform data struct, add kernel docs describing its members.
