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.
