Drop statuses when not needed.

This looks incomplete.

It does not look like you tested the DTS against bindings. Please run
`make dtbs_check` (see
Documentation/devicetree/bindings/writing-schema.rst or
https://www.linaro.org/blog/tips-and-tricks-for-validating-devicetree-sources-with-the-devicetree-schema/
for instructions).

Are you sure this is part of SoC? It is rather unusual... I would say
this would be the first SoC, where GPIO pins must be an I2C.
