[PATCH v5 2/2] dt-bindings: iio: proximity: document LIDAR-Lite v3 fallback compatible

[Rodrigo Gobbi <rodrigo.gobbi.7@gmail.com>]

PulsedLight was acquired by Garmin, who now sells the LIDAR-Lite v3.
It is pin-compatible with the v2, and the driver already matches it
directly: commit b257c1a45e99 ("iio: pulsedlight-lidar-lite-v2: add
lidar-lite-v3 property") added a "grmn,lidar-lite-v3" of_device_id
entry, so no driver changes are needed here.

Document it with "pulsedlight,lidar-lite-v2" as a fallback compatible.
