feat(spmc): add support for v1.1 FF-A memory data structures
Add support for the FF-A v1.1 data structures to the EL3 SPMC
and enable the ability to convert between v1.0 and the v1.1
forwards compatible data structures.
The SPMC now uses the v1.1 data structures internally and will
convert descriptors as required depending on the FF-A version
supported by the calling partition.
