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.
