PATCH 1/1 arm: berlin: remove non-necessary flush_cache_all()
I believe the flush_cache_all() after scu_enable() is to "Ensure that the data accessed by CPU0 before the SCU was initialised is visible to the other CPUs." as commented in scu_enable(). So flush_cache_all() here is a duplication of the one in scu_enable(), remove it.
