Since commit 9f2ff99c7f2 ("qdev-monitor: print the device's clock
with info qtree") we can display the clock frequencies in the
monitor. Use the recently introduced freq_to_str() to display
the frequencies using the closest SI unit (human friendlier).

Before:

  (qemu) info qtree
  [...]
  dev: xilinx,zynq_slcr, id ""
    clock-in "ps_clk" freq_hz=3.333333e+07
    mmio 00000000f8000000/0000000000001000

After:

  dev: xilinx,zynq_slcr, id ""
    clock-in "ps_clk" freq_hz=33.3 MHz
    mmio 00000000f8000000/0000000000001000
