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.

help
This Firmware Framework(FF) for Arm A-profile processors describes
interfaces that standardize communication between the various
software images which includes communication between images in
the Secure world and Normal world. It also leverages the
virtualization extension to isolate software images provided
by an ecosystem of vendors from each other.
This driver provides interface for all the client drivers making
use of the features offered by ARM FF-A.
