feat(ethos-n): add support to set up NSAID

For the TZC to allow the Arm(R) Ethos(TM)-N NPU to access the buffers
allocated in a protected memory region, it must include the correct
NSAID for that region in its transactions to the memory.  This change
updates the SiP service to configure the NSAIDs specified by a platform
define. When doing a protected access the SiP service now configures the
NSAIDs specified by the platform define. For unprotected access the
NSAID is set to zero.
