Sudeep Holla 714be77e97 firmware: arm_ffa: Add support for SMCCC as transport to FFA driver 
There are requests to keep the transport separate in order to allow
other possible transports like virtio. 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.
