We need the regulators for the CPU rails to start before the cpufreq
driver starts so cpufreq can talk to them, and since the regulators may
be SPI attached this means we also need the SPI controller to start
before cpufreq.  cpufreq starts at vanilla init time.

There's an approach being looked at for handling this for devices but
for deviceless stuff like cpufreq we've nothing.
