dt-bindings: iio: io-channel-mux: allow duplicate channel, labels 



This is needed since an empty channel label is used to indicate an
unused channel, and there can be more that one of those.

Fixes the following problem reported by dtbs_check:
envelope-detector-mux: channels: ['', '', 'sync-1', 'in', 'out', 'sync-2', 'sys-reg', 'ana-reg'] has non-unique elements
