Heh this was totally not working and had several copy paste bugs..
Instead of including more files, let's just make them dummy inline
functions.

Subject: [PATCH] omap: Disable omap_read/write functions for omap2+
These should be now long gone and break multi-omap support for omap1
as the cpu_class_is_omap1() won't work until the SOC is detected.
So just disable them for omap2+.
