ARM: EXYNOS: Use cpuidle_register 



Use the cpuidle generic function 'cpuidle_register'. That saves us
from some extra lines of code and unneeded variables.

A side effect of this change is a bug fix where before the cpuidle
driver was registered for each_online_cpu and now it is for
each_possible_cpu.
