[PATCH] arm: berlin: remove non-necessary flush_cache_all()

[Jisheng Zhang]

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.
