Subject: [PATCH v2 2/2] dt-bindings: iio: gyro: Add DT binding doc for ADXRS290

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

Signed-off-by: Nishant Malpani <nish.malpani25@...il.com>

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