Test

Built both gateware & firmware of a small system, loaded in a Kasli-SoC.
artiq_sinara_tester blinked the LED.

The following test code was inserted into the main_core0() function in artiq-zynq runtime after "NAR3/Zynq7000 starting..." was logged.

    let clk_frequency = Clocks::get().cpu_6x4x();
    info!("cpu_6x4x: {}", clk_frequency);

Clocks was imported from libboard_zynq::clocks::Clocks in prior.
It produced this trace in serial logging.

[     0.000067s]  INFO(runtime): NAR3/Zynq7000 starting...
[     0.005235s]  INFO(runtime): cpu_6x4x: 999999990

It was 799999992 before this patch.
