[PATCH v2 0/4] iio: vcnl4000: Export near level property for proximity sensor

If an object can be considered close to the device that has the proximity
sensor built in is hardware dependent. Allowing to configure the property via
device tree allows to export this device specific value to userspace via
ext_info. This is useful for e.g. iio-sensor-proxy.

This came up when adding proximity support to iio-sensor-proxy [1], [2], it is
not meant as a vcnl4000 thing but rather as something useful for other proximity
sensors too in the future.

Changes from v1:
- as per review comments by Jonathan Cameron

Document new sysfs file in Documentation/ABI/testing/sysfs-bus-iio-proximity
- convert bindings to yaml
- bindings: fix typo in near-level property
