The SCPI clk driver registers the virtual cpufreq device that kicks off
initialisation of the SCPI cpufreq driver. Make the dependendency
explicit in Kconfig.

That's not a dependency. Any other part of the kernel can add this
*virtual* cpufreq device to get it going.

Any part can add the virtual cpufreq device but for scpi-cpufreq it is
done by clk-scpi. I can re-word it for clarity.

But, we do have dependency the other way round. clk_get() will fail
for the cpufreq driver if SCPI-clk driver is missing and perhaps
that's what you need to mention in the changelog.

This looks fine.

I'll send an updated version to be picked up.

Thanks for taking a look.
