dt-bindings: iio: adc: Add common-mode-channel property
...
There are ADCs that are differential but support to measure single-ended
signals on the same channels by connecting a constant voltage to the
negative input pin.
This property allows to properly define a single-ended channel that
requires two inputs to be specified. Software can use the presence of
this property to mark the channel as not differential.

dt-bindings: iio: adc: Add single-channel property
...
Devices that have both single-ended channels and differential channels
cause a bit of confusion when the channels are configured in the
devicetree.
Clarify difference between these two types of channels for such devices
by adding single-channel property alongside diff-channels. They should
be mutually exclusive.
Devices that have only single-ended channels can still use reg property
to reference a channel like before.

dt-bindings: iio: adc: drop redundant type from label
...
dtschema defines label as string, so $ref in other bindings is
redundant.

dt-bindings: drop redundant part of title of shared bindings
...
The Devicetree bindings document does not have to say in the title that
it is a "binding", but instead just describe the hardware. For shared
(re-usable) schemas, name them all as "common properties".

dt-bindings:iio:adc: add generic settling-time-us and oversampling-ratio channel properties
...
Settling time and over sampling is a typical challenge for different IIO ADC
devices. So, introduce channel specific settling-time-us and oversampling-ratio
properties to cover this use case.

Each driver that uses this will need to use a $ref
We can't always enable it like most of the generic bindings due to
channel@X matching far more widely than IIO.
