Subject: [PATCH 3/6] cpufreq/drivers/arm_big_little: Remove cooling device usage

The cpufreq_cooling_unregister() function uses now the policy to
unregister itself. The only purpose of the cooling device pointer is
to unregister the cpu cooling device.

As there is no more need of this pointer, remove it.
