dt-bindings: pinctrl: mediatek: Fix child node name patterns

The child node name patterns in Mediatek pinctrl bindings don't match
reality. I don't know where '-[0-9]+$' came from, but I don't see any nodes
with a matching pattern. Also, patterns such as 'pins' or 'mux' are
ambiguous because any prefix or suffix is allowed. If that's desired, it
should be explicit.
