add device-tree binding documentation for Cypress cypd4226 type-C
controller's I2C interface. It is a standard I2C slave with GPIO
input as IRQ interface.

Signed-off-by: Wayne Chang <waynec@nvidia.com>

V2 -> V3:fix additionalProperties warning on new schema
V1 -> V2:based on the review comments. Fix some addressed issues on
description, interrupts, cypress,firmware-build, connector, and 
additionalProperties properties. And also remove the status in the example.
