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.
