arm: omap-common: add secure rom call API for secure devices
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.
