TBB: add mbedTLS authentication related libraries
This patch adds the following mbedTLS based libraries:
* Cryptographic library
It is used by the crypto module to verify a digital signature
and a hash. This library relies on mbedTLS to perform the
cryptographic operations. mbedTLS sources must be obtained
separately.
Two key algorithms are currently supported:
* RSA-2048
* ECDSA-SECP256R1
The platform is responsible for picking up the required
algorithm by defining the 'MBEDTLS_KEY_ALG' variable in the
platform makefile. Available options are:
* 'rsa' (for RSA-2048) (default option)
* 'ecdsa' (for ECDSA-SECP256R1)
Hash algorithm currently supported is SHA-256.
* Image parser library
Used by the image parser module to extract the authentication
parameters stored in X509v3 certificates.
