Andre Przywara 240770989f refactor(cpufeat): align FEAT_SB to new feature handling ... FEAT_SB introduces a new speculation barrier instruction, that is more lightweight than a "dsb; isb" combination. We use that in a hot path, so cannot afford and don't want a runtime detection mechanism. Nevertheless align the implementation of the feature detection part with the other features, but renaming the detection function, and updating the FEAT_DETECTION code. Also update the documentation.
