feat(spmd): enable handling of FF-A SMCs with the SPMC at EL3
Any FF-A SMC that arrives from the normal world is handled by the
SPMD before being forwarded to the SPMC. Similarly any SMC
arriving from the secure world will hit the SPMC first and be
forwarded to the SPMD if required, otherwise the SPMC will
respond directly.
This allows for the existing flow of handling FF-A ABI's when
the SPMC resides at a lower EL to be preserved.
In order to facilitate this flow the spmd_smc_forward function
has been split and control is either passed to the SPMC or it is
forwarded as before. To allow this the flags and cookie parameters
must now also be passed into this method as the SPMC must be able to
provide these when calling back into the SPMD handler as appropriate.

feat(spmd): update SPMC init flow to use EL3 implementation
Allow the SPMD to initialise an SPMC implementation at EL3 directly
rather than at a lower EL.
This includes removing the requirement to parse an SPMC manifest to
obtain information about the SPMC implementation, in this case since the
SPMD and SPMC reside in the same EL we can hardcode the required
information directly.

feat(rme): add dummy realm attestation key to RMMD
Add a dummy realm attestation key to RMMD, and return it on request.
The realm attestation key is requested with an SMC with the following
parameters:
* Fid (0xC400001B2).
* Attestation key buffer PA (the realm attestation key is copied
at this address by the monitor).
* Attestation key buffer length as input and size of realm
attesation key as output.
* Type of elliptic curve.
