This patch adds a crypto driver which utilizes the ARM® TrustZone® CryptoCell-712 to verify signature and hash during Trusted Board Boot. Along with this driver, the CryptoCell SBROM library is required to successfully build the BL image. The path to this library is specified via the `CCSBROM_LIB_PATH` variable. Please note that, mbedTLS is still required to do the X509 certificate ASN.1 parsing and CryptoCell is only utilized for signature and hash verification.
