Subject: [PATCH v3 2/2] dt-bindings: iio: proximity: Add Lidar-lite-v2 and v3

Since v2 is not a trivial device, add it to a dedicated place. The v3 is
similar to the v2 version, so add it as a fallback to the v2. Both versions
are already supported by the driver.

+description: |
+  Support for LIDAR_Lite v2 and v3 laser rangefinders. These devices
+  can use a simple I2C communication bus or can operate in a PWM mode using a
+  mode control pin to trigger acquisitions and return the measured distance.
+  It also have a power enable pin, which can be used to shut off the device.
