Andre Przywara d5384b69d1 refactor(cpufeat): enable FEAT_NV2 for FEAT_STATE_CHECKED ... At the moment we only support for FEAT_NV2 to be either unconditionally compiled in, or to be not supported at all. Add support for runtime detection (CTX_INCLUDE_NEVE_REGS=2), by splitting get_armv8_4_feat_nv_support() into an ID register reading function and a second function to report the support status. That function considers both build time settings and runtime information (if needed), and is used before we access the VNCR_EL2 system register. Also move the context saving code from assembly to C, and use the new is_feat_nv2_supported() function to guard its execution. Change the FVP platform default to the now supported dynamic option (=2), so the right decision can be made by the code at runtime.
