Implement support for SMCCC v1.1
SMCCC v1.1 comes with a relaxed calling convention for AArch64 callers. The caller only needs to save x0-x3 before doing an SMC call. This patch adds support for SMCCC_VERSION and SMCCC_ARCH_FEATURES. Refer to "Firmware Interfaces for mitigating CVE_2017_5715 System Software on Arm Systems"[0] for more information.
