Adds a generic C-callable API for making secure ROM calls on OMAP and OMAP-compatible devices. This API provides the important function of flushing the ROM call arguments to memory from the cache, so that the secure world will have a coherent view of those arguments. Then is simply calls the omap_smc_sec routine.
