Subject: [PATCH RFC 2/4] dt-bindings: clock: break out mediatek,ethsys into
 its own header

The ethsys clocks of MT7981 and MT7986 are identical. In order to
de-duplicate both clock drivers, start with putting ethsys into a
header files of its own, so it can be used by both SoCs.
Propagate this change also to mt7986a.dtsi which is the only user.
