cpufreq: Init cpufreq only for present CPUs
for_each_possible_cpu() is currently used to initialize cpufreq.
However, in cpu_dev_register_generic(), for_each_present_cpu()
is used to register CPU devices which means the CPU devices are
only registered for present CPUs and not all possible CPUs.
With nosmp or maxcpus=0, only the boot CPU is present, lead
to the cpufreq probe failure or defer probe due to no cpu device
available for not present CPUs.
Change for_each_possible_cpu() to for_each_present_cpu() in the
above cpufreq drivers to ensure it only registers cpufreq for
CPUs that are actually present.
Fixes: b0c69e1214bc ("drivers: base: Use present CPUs in GENERIC_CPU_DEVICES")
