[PATCH] dt-bindings: usb: xlnx,usb2: Make clocks required

Add s_axi_aclk AXI4 clock support as a required property. Traditionally
this IP was used on MicroBlaze platforms which had fixed clocks enabled
all the time. But since it is a PL IP, it can also be used on SoC
platforms like Zynq UltraScale+ MPSoC which combines processing system
(PS) and user programmable logic (PL) into the same device. On these
platforms instead of fixed enabled clocks it is mandatory to explicitly
enable IP clocks for proper functionality.

So make clocks and clock-names required properties.
