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.

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.
