No, we can't do it this way, it breaks things. We need to first
convert everything to use the new GPMC driver, then move it.

Let's not put it into MFD. This is a bus driver. But that
decision can wait as we cleary have quite a few things to convert
first under arch/arm/mach-omap2.

It's a parallel bus driver, not memory not misc, not MFD.
