Add the support to save Nwd's floating point registers before switching
to SEL0 and then restore it after coming out of it. Emit a warning
message if SPM_MM is built with CTX_INCLUDE_FPREGS == 0
There is no need to save FP registers of SEL0 because secure partitions
run to completion.
This change is used to prevent context corruption if secure partition
enabled and Nwd decide to use floating point registers.

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.
