Some old MediaTek clock drivers are starting the clock count (so, the clock ID) from one instead of zero and this is logically incorrect, as we should start from 0. During a cleanup an issue emerged due to that and the cleanest and shortest way to keep devicetree backwards compatibility while still performing the well deserved cleanup is to add a dummy clock where needed, with ID 0.
