ARM: EXYNOS: pm: Move call to flush_cache_all() before outer_flush_all()
Flushing L1 cache might cause data to be stored to L2 cache, so it is
more reasonable to flush L1 cache first and only then L2 cache.
This patch moves call to flush_cache_all() in exynos_cpu_suspend()
before outer_flush_all() to make sure that all data are flushed
correctly. In addition flushing is enabled for all Exynos SoCs to
prevent any data loss.
