Aleksander Morgado 9ec90d9a11 core,plugins: don't assume 'CS' supported when '2G' supported 
We will not report 'CS' as a supported mode every time '2G' is supported. This
actually was forcing all plugins to handle a 'CS' fallback when they didn't have
CS-specific mode setup. So, to simplify things, we will only report 'CS' as
supported for those plugins which actually allow to select 'CS' mode (e.g. the
'wavecom' plugin).
