The best thing to do is to add an EMIF driver stub that is initialized
based on hwmod data, rather than hacking this into the existing SDRC.

I don't know what the current state of the EMIF driver is. Aneesh,
do you know what the current status is?

If it's not going upstream for some reason, then I'd suggest adding
arch/arm/mach-omap2/emif.c for now.
