I've sent a patch [1] relaxing the requirement for clock-names in the binding.
There's no reason to make clock-names mandatory, as there is and there always
will be one single clock for each GCE mailbox - and also the driver is not
trying to get the clock by name, but rather gets the clock at index 0 anyway.

Please drop this patch.

Cheers,
Angelo
