On Exynos5420 we support 8 cpufreq steps (600-1300 MHz) for LITTLE and
12 steps for big core (700-1800 MHz). Add respective cooling cells.

Though it wouldn't matter (for the issue you are getting), but this should be
added for all the CPUs in case some other CPU is booted first.

Thanks! I'll fix it also for patch 2/3.

Best regards,
