Allow qcom-hw driver to initialise right after the cpufreq and thermal
subsystems are initialised in core_initcall so we get earlier access to
thermal mitigation.

Hi Amit,

Booting linux-next on my db845c (and SDM850 laptop) I can see that the
device probes in /sys/bus/platform/drivers/qcom-cpufreq-hw, but
/sys/devices/system/cpu/cpufreq is empty.

Reverting this change gives me cpufreq back. Can you please have a look
at this?

Regards,
Bjorn
