Add s_axi_aclk AXI4 clock support. Traditionally this IP was used on microblaze platforms which had fixed clocks enabled all the time. But since its 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 clock a required property and also define max supported clock constraints.
