Marc Bonnici 7affa25cad 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.

Marc Bonnici 5096aeb2ba 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.
