Add devicetree binding document for ADXRS290, a dual-axis MEMS gyroscope.
Reviewed-by: Rob Herring <robh@xxxxxxxxxx>
Signed-off-by: Nishant Malpani <nish.malpani25@xxxxxxxxx>

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'
