SPM: SGI: Map memory allocated for secure partitions
The secure partition manager reserves chunks of memory which are used
for the S-EL0 StandaloneMM image and the buffers required for
communication between the Non-Secure world with the StandaloneMM
image. Add the memory chunks to relevant arrays for mapping the
regions of memory with corresponding attributes.
