mtd: nand: ams-delta: convert to platform driver
In its current form, the driver may interfere with different hardware on
different boards if built into the kernel, hence is not suitable for
inclusion into a defconfig, inteded to be usable with multiple OMAP1 cpu and
machine types.
Convert it to a platform driver, that should be free from this issue.
Created and tested against linux-2.6.37-rc5 on Amstrad Delta.
