[v4 2/2] dt-bindings: iio: gyro: Add DT binding doc for ADXRS290

[Nishant Malpani]

Add devicetree binding document for ADXRS290, a dual-axis MEMS gyroscope.

Reviewed-by: Rob Herring <robh@kernel.org>
Signed-off-by: Nishant Malpani <nish.malpani25@gmail.com>

No changes in v4.

No changes in v3.

Changes in v2:
  - use 'const' instead of 'enum' while setting the compatible string
    since only a single item is expected
  - add 'additionalProperties: false'

Applied to the togreg branch of iio.git and pushed out as testing for the
autobuilders to play with them.

Note this won't make the coming merge window, so will go in next cycle.
