This patch adds header files with required declarations and macro definitions to enable integration with CryptoCell SBROM version `CC712 – Release 1.0.0.1061`. These headers enable ARM Trusted Firmware to build and link with CryptoCell SBROM library. Change-Id: I501eda7fe1429acb61db8e1cab78cc9aee9c1871 Signed-off-by: Soby Mathew <soby.mathew@arm.com>
