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.

I've not converted the vcnl4000 binding docs to yaml but can do so as part of
this series in a v2 if the approach makes sense.

Changes from v2:
- as per review comment by Lars-Peter Clausen
  https://lore.kernel.org/linux-iio/c787921f-c412-4986-14ea-e31b531d3d5b@metafoo.de/
  Switch sysfs name to `nearlevel`
- as per review comment by Nishant Malpani
  https://lore.kernel.org/linux-iio/f5ea512c-d427-94c7-cf5f-f1300cbd4aa3@gmail.com/
  Add manufacturer do binding document name
- as per review comments by Andy Shevchenko
  - Drop superfluous blank line
  - Check return value of device_property_read_u32 for '!= 0' instead of '< 0'

Changes from v1:
- as per review comments by Jonathan Cameron
  https://lore.kernel.org/linux-iio/20200221120519.43b72007@archlinux/
  Document new sysfs file in Documentation/ABI/testing/sysfs-bus-iio-proximity
- convert bindings to yaml
- bindings: fix typo in near-level property
