dt-bindings: crypto: Add TI SA2UL crypto accelerator documentation
The Security Accelerator Ultra Lite (SA2UL) subsystem provides hardware
cryptographic acceleration for the following use cases:
* Encryption and authentication for secure boot
* Encryption and authentication of content in applications
requiring DRM (digital rights management) and
content/asset protection
SA2UL provides support for number of different cryptographic algorithms
including SHA1, SHA256, SHA512, AES, 3DES, and various combinations of
the previous for AEAD use.
