[PATCH v2 1/2] dt-bindings: clock: sophgo: Add top misc controller of CV18XX/SG200X series SoC

[Inochi Amaoto]

CV18XX/SG200X series SoCs have a special top misc system controller,
which provides register access for several devices. In addition to
register access, this system controller also contains some subdevices
(such as dmamux).

Add bindings for top misc controller of CV18XX/SG200X series SoC.
