feat(tsp): add FF-A support to the TSP
This patch adds the FF-A programming model in the test
secure payload to ensure that it can be used to test
the following spec features.
1. SP initialisation on the primary and secondary cpus.
2. An event loop to receive direct requests and respond
with direct responses.
3. Ability to receive messages that indicate power on
and off of a cpu.
4. Ability to handle a secure interrupt.

fix(spmc): fix relinquish validation check
The current implementation expects that the endpoint IDs of all
participants of a memory transaction to be listed in the relinquish
descriptor. As per the FF-A spec, aside from the current partition
ID, only the IDs of stream endpoints whose behalf it is relinquishing
the memory region must be specified.
The current implementation does not currently support proxy endpoints
therefore ensure that the endpoint count is always equal to 1 and
no stream endpoint IDs are specified and instead just verify the
caller is a valid participant in the memory transaction.
Additionally reuse the updated check in the retrieve request flow
for additional verification.

This allows for platform specific functionality to be performed

Note the hooks must be placed in the initial share request and final

place in the normal world without visibility of the SPMC.

Enable the SPMC to set the bit for v1.1 callers or v1.0

A partition can request the use of the FF-A boot protocol via
an entry in its manifest along with the register (0-3)
that should be populated with a pointer to a data structure
containing boot related information. Currently the boot
information consists of an allocated memory region
containing the SP's manifest, allowing it to map and parse
any extra information as required.
This implementation only supports the v1.1 data structures
and will return an error if a v1.0 client requests the usage
of the protocol.

- FFA_MEM_RETRIEVE_RESP
- FFA_MEM_RELINQUISH
- FFA_MEM_RECLAIM
- FFA_MEM_FRAG_RX

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.
