In preparation for adding the EL3 SPMC configuration as defined in the FF-A specification, restructure the existing SPM_MM code. With this restructuring of the code, the 'spm_mm' directory is renamed as 'spm' and the code inside has been split into two sub-directories named 'common' and 'spm_mm'. The code in 'spm_mm' directory contains the code that implements the MM interface. In subsequent patches, the 'spmc' directory will be introduced under the 'spm' directory providing the code that implements the 'FF-A' interface. Currently the common functionality for S-EL1 partitions is limited to assembler functions to enter and exit an SP synchronously.
