annotations: remove configs that are undefined across all arches/flavours

Sometimes certain config options are removed in new kernels, so when
annotations is updated these options result to be undefined across all
architectures and flavours, in this case it's much more clean to simply
drop them from annotations (considering that the kernel doesn't support
them anymore).
