[PATCH 3/8] dt-bindings: clock: clocking-wizard: Make s_axi_aclk optional for static-config

[Shubhrajyoti Datta]

In static-config mode the AXI bus interface is unused, so s_axi_aclk
is not required. Allow clocks/clock-names to have only one entry
(clk_in1) when xlnx,static-config is present and enforce two entries
otherwise. Update the static-config example accordingly.
