arm64: Adapt stage_entry to make it usable by secmon

stage_entry is the best place to enter for secmon, since it sets up all the
    stacks right. The only need we need to take care is losing out on the parameter
    passed to secmon. This patch adds an entry point for secmon rmodule and moves
    the argument from x0 to x25, which is restored just before the jump to c_entry
