mbedtls: Use `MBEDTLS_SHA256_SMALLER` in ARM platforms
Antonio Nino Diaz authored
This options enables an implementation of SHA-256 that has a smaller
code footprint (~1.6 KB less) but is also ~30% slower. For ARM
platforms, code size is currently considered more important than
execution speed in the mbed TLS crypto module.

Added a small note about this option to the documentation of the
authentication framework.
