dt-bindings: ARM: Mediatek: Remove msdc binding of MT8192 clock

The code controlling msdc clock gate was moved inthe the consumer, the MMC
driver. This node did never represent a working implementation of any
peripheral. It was just a lonely clock gate that wasn't used. Delete the
binding description of this node.
