This patch seems to be irrelevant to the rest of this series. Anyway, 
the changes itself are fine, except that I can see more functions that 
could be made static as well:
 - exynos_cpuidle_init(),
 - exynos_cpufreq_init().

In fact, they both could be probably eliminated, as they are just 
oneliners doing things that could be done in exynos_dt_machine_init() 
directly.

So, if you are doing this kind of cleanup, you could do this as well and 
probably also replace platform_device + platform_device_register() with 
platform_device_register_simple() for cpuidle, to reduce line count and 
make it consistent with cpufreq.

Best regards,
Tomasz
