feat(fvp): add plat hook for memory transactions
Add call to platform hooks upon successful transmission of a
memory transaction request and as part of a memory reclaim request.
This allows for platform specific functionality to be performed
accordingly.
Note the hooks must be placed in the initial share request and final
reclaim to prevent order dependencies with operations that may take
place in the normal world without visibility of the SPMC.
Add a dummy implementation to the FVP platform.

feat(spmc/mem): add FF-A memory management code
Originally taken from the downstream Trusty SPD [1]
implementation and modified to integrate with
the EL3 SPMC internals.
Add support to the EL3 SPMC for a subset of the FF-A
memory management ABIs:
- FFA_MEM_SHARE
- FFA_MEM_LEND
- FFA_MEM_RETRIEVE_REQ
- FFA_MEM_RETRIEVE_RESP
- FFA_MEM_RELINQUISH
- FFA_MEM_RECLAIM
- FFA_MEM_FRAG_RX
- FFA_MEM_FRAG_TX
This implementation relies on a datastore allocated in
platform specific code in order to store memory descriptors
about ongoing memory transactions. This mechanism
will be implemented in the following commit.
