Adam Ford 68a51cc8ec arm: omap3: Make some memory functions static and clean headers
There are a few memory functions for both the emif4 (AM3517)
and sdrc (OMAP35/DM37) code that can be defined as static,
because those functions are not used externally. Make them
static and clean up some of the corresponding headers.
