mtd: nand: ams-delta: convert to platform driver

Browse Source 
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.
