Geert Uytterhoeven c81407fe57 cpufreq: cpufreq-dt: Restore default cpumask_setall(policy->cpus) 
Commit 34e5a5273d ("cpufreq: cpufreq-dt: extend with
platform_data") changed cpufreq_init() to only call
cpumask_setall(policy->cpus) if the platform data indicates that all
CPUs share the same clock. Before, cpufreq_generic_init() did this
unconditionally.

This causes a crash on r8a7791/koelsch when resuming from s2ram:

Restore the old default of calling cpumask_setall(policy->cpus) if no
platform data is available to fix this.
