Subject: [PATCH v2] dt-bindings: iio: gyroscope: bosch,bmg160: correct number of pins

BMG160 has two interrupt pins to which interrupts can be freely mapped.
Correct the schema to express such case and fix warnings like:

  qcom/msm8916-alcatel-idol347.dtb: gyroscope@68: interrupts: [[97, 1], [98, 1]] is too long

However the basic issue still persists - the interrupts should come in a
defined order.

Signed-off-by: Krzysztof Kozlowski <krzysztof.kozlowski@...aro.org>

Changes since v1:
1. Accept also INT2 as one interrupt (Jonathan).
