Add platform specific TRNG driver
Adds platform specific TRNG driver to Crypto opteesp deployment.
Fetches and builds the TZ-TRNG driver from its external
repo and includes it when the crypto/opteesp is built for
the arm/fvp/fvp_base_revc-2xaemv8a platform. Device region
information provided as external configuration data is
not yet integrated to the TRNG hardware is not yet used.
