EL3-SPMC currently only supports sharing and lending memory
from NS to the secure world (DONATE is not supported).
That means that the NS bit should always be set,
except for a few cases:
* The operation is a LEND (NS->S), or
* The NS bit is not supported, i.e., v1.0 where the bit
was not explicitly negotiated.
