cpufreq: cpu0: rename driver and internals to 'cpufreq_dt' 



The naming convention of this driver was always under the scanner, people
complained that it should have a more generic name than cpu0, as it manages all
CPUs that are sharing clock lines.

Also, in future it will be modified to support any number of clusters with
separate clock/voltage lines.

Lets rename it to 'cpufreq_dt' from 'cpufreq_cpu0'.

Generic CPU0 cpufreq driver

Generic cpufreq driver



It is a generic cpufreq driver for CPU0 frequency management.  It

supports both uniprocessor (UP) and symmetric multiprocessor (SMP)

systems which share clock and voltage across all CPUs.

It is a generic DT based cpufreq driver for frequency management.  It supports

both uniprocessor (UP) and symmetric multiprocessor (SMP) systems which share

clock and voltage across all CPUs.



Both required and optional properties listed below must be defined

under node /cpus/cpu@0.
