dt-bindings: drop redundant part of title (end, part three)

The Devicetree bindings document does not have to say in the title that
it is a "binding", but instead just describe the hardware.

Drop trailing "bindings" in various forms (also with trailing full
stop):

find Documentation/devicetree/bindings/ -type f -name '*.yaml' \
-not -name 'trivial-devices.yaml' \
-exec sed -i -e 's/^title: \(.*\) [bB]indings\?\.\?$/title: \1/' {} \;

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
arch/arm/boot/dts/at91-tse850-3.dt.yaml

dt-bindings: iio: io-channel-mux: add optional #io-channel-cells

Needed for in-kernel use of the child channels of the mux.

Fixes problems like this, reported by dtbs_check:
adc0mux: '#io-channel-cells' does not match any of the regexes: 'pinctrl-[0-9]+'

dt-bindings: iio: io-channel-mux: Add property for settle time

Hardware may require some time for the muxed analog signals to settle
after the muxing is changed. Allow this time to be specified in the
devicetree.
