This adds support for an additional clock for the dwc2 core in case
there is another clock to the phy which must be enabled.

My bot found errors running 'make dt_binding_check' on your patch:

See https://patchwork.ozlabs.org/patch/1424674

This check can fail if there are any dependencies. The base for a patch
series is generally the most recent rc1.

If you already ran 'make dt_binding_check' and didn't see the above
error(s), then make sure 'yamllint' is installed and dt-schema is up to
date:

pip3 install dtschema --upgrade

Please check and re-submit.

Ok, this can be fixed by adding a "minItems" property to clocks and
clock-names. Will do next round.

Anything more to say to this series?
