In order to also enable in-kernel users of FFA interface, let us add simple set of operations for such devices. The in-kernel users are registered without the character device interface.

So let us keep the SMCCC transport specific routines abstracted. It is kept simple for now. Once we add another transport, we can develop better abstraction.
