[PATCH v2 7/8] dt-bindings: i2c: realtek,rtl9301-i2c: extend for RTL9607C support

[Rustam Adilov <adilov@disroot.org>]

Add the "realtek,rtl9607-i2c" compatible for i2c controller on the
RTL9607C SoC series.

Add a clocks property to the properties since RTL9607C requires it
along with the realtek,scl. And because RTL9607C is the only one that
requires the new clocks property, add "clocks: false" to everything
else.
