[SWDEV-484382] Fix VCLK/DCLK outputs for monitor, static, metric

Units were off and VCLK/DCLK outputs were not coming in
properly through amdsmi_get_clk_freq()

Now we match units sent back through rsmi_dev_gpu_clk_freq_get (MHz).

CLI now shows maximum of 2 VCLK/DCLKs otherwise shows N/A if there
is no current_freq listed.
