[PATCH v8] dt-bindings: iio: Add Infineon DPS310 sensor documentation

[Eddie James]

The DPS310 is a barometric pressure and temperature sensor with
an I2C interface. Remove it from trivial-devices.yaml and add its
own documentation, with a hwmon iio channel consumer example.

Changes since v7:
 - Add consumer example and update commit message slightly

Ah. Sorry I was unclear on my feedback wrt to this. I was just
looking for a statement in the commit message to say that you were
doing this to allow for consumers such as the iio/hwmon bridge.
I wasn't expecting any change to the example.

+ the supplies as per reply on previous version I just sent.
