Register NS shared memory for SP's activity logs and TA sessions

This patch registers NS memory buffer with the secure payload using
two different functions IDs - REGISTER_LOGBUF, REGISTER_REQBUF.

a. The SP uses the log-buffer to store its activity logs, in a
pre-decided format. This helps in debugging secure payload's issues.
b. The SP uses the req-buffer to get the parameters required by
sessions with Trusted Applications.
