Subject: [PATCH v5 3/3] dt-bindings: max77705: add interrupt-controller
 property

Add interrupt-controller property, because max77705 has dedicated interrupt
source register to determine which sub device triggered an interrupt.

Changes for v5:
- group interrupt properties together, including #interrupt-cells

Changes in v4:
