Makes sense but please also add a check in exynos_sys_powerdown_conf() for
!pmu_data or a comment for that. For current architecture, this will not
happen but you are adding different usage thus forcing reader to find the
dependencies on his own (dependecies are already spread all over for ARMv7).

Best regards,
Krzysztof
