Accelerated GCM AES-128 Cipher

Accelerated AES-GCM-128 cipher for the mbed TLS API using the CRYPTOACC or SE peripheral.

This module implements the GCM AES-128 cipher, as defined in D. McGrew, J. Viega, The Galois/Counter Mode of Operation (GCM), Natl. Inst. Stand. Technol. For more information on GCM, see NIST SP 800-38D: Recommendation for Block Cipher Modes of Operation: Galois/Counter Mode (GCM) and GMAC.
