feat(el3-spmc): make platform logical partition optional

Prior to this commit a logical platform specific partition is added when
compiling with SPMC at EL3. Not all platform need to add a logical
platform so make this optional.

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.

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.

feat(spmc): add support for FF-A power mgmt. messages in the EL3 SPMC

This patch adds support for forwarding the following PSCI messages
received by the SPMC at EL3 to the S-EL1 SP if the SP has indicated
that it wishes to receive the appropriate message via its manifest.

1. A PSCI CPU_OFF message in response to a cpu hot unplug request
from the OS.
2. A message to indicate warm boot of a cpu in response to a cpu
hot plug request from the OS.
3. A PSCI CPU_SUSPEND message in response to a cpu idle event
initiated from the OS.
4. A message to indicate warm boot of a cpu from a shallow power
state in response to a cpu resume power event.

This patch also implements the FFA_SECONDARY_EP_REGISTER function to
enable the SP specify its secondary entrypoint.

feat(spmc/lsp): add logical partition framework

Introduce a framework to support running logical
partitions alongside the SPMC in EL3 as per the
v1.1 FF-A spec.

The DECLARE_LOGICAL_PARTITION macro has been added to
simplify the process to define a Logical Partition.
The partitions themselves are statically allocated
with the descriptors placed in RO memory.

It is assumed that the MAX_EL3_LP_DESCS_COUNT will
be defined by the platform.

feat(spmc): add FF-A secure partition manager core

This patch introduces the core support for enabling an SPMC in EL3
as per the FF-A spec.

The current implemented functionality is targeted to enable
initialization of the SPMC itself and initial support for
bringing up a single S-EL1 SP.

This includes initialization of the SPMC's internal state,
parsing of an SP's manifest, preparing the cpu contexts and
appropriate system registers for the Secure Partition.

The spmc_smc_handler is the main handler for all incoming SMCs
to the SPMC, FF-A ABI handlers and functionality will
be implemented in subsequent patches.
