[PATCH 0/2] PBL: enable hash functions for Vendor Authorized Boot

Altera's Vendor Authorized Boot (VAB) uses a sha384 hash for verifying
the second stage boot loader.

As preparation for adding VAB, make the sha384 and sha512 hash functions
available in the PBL.

Loading the second stage loader from flash and verifying the signature
will follow as separate patch series.
