cpufreq: cpufreq-dt: extend with platform_data
This commit extends the cpufreq-dt driver to take a platform_data
structure. This structure is for now used to tell the cpufreq-dt
driver the layout of the clocks on the platform, i.e whether all CPUs
share the same clock or whether each CPU has a separate clock.
