Add ARMv8.3 pointer authentication support
ARMv8.3-PAuth adds functionality that supports address authentication of the contents of a register before that register is used as the target of an indirect branch, or as a load. This feature is supported only in AArch64 state. This feature is mandatory in ARMv8.3 implementations. This patch adds the functionality needed for platforms to provide authentication keys for the TF-A Test Framework, and a new option (ENABLE_PAUTH) to enable pointer authentication in the framework itself. This option is disabled by default. Pointer authentication support has been added to FVP.
