Gack. This will break on non-OMAP ARM platforms now too, so it needs to be
depends on ARCH_OMAP instead of ARM.

Tony, can I get an Acked-by so I can apply this to next/cleanup? Sam, if
you prefer to apply it yourself, let me know.

It uses OMAP-only header files, and since it's an OMAP companion chip
it doesn't really make sense to enable on other platforms.
