Subject: [PATCH 2/2] arm: exynos: Clear ENABLE_WAKEUP_SW bit when entering suspend

From: Jonathan Kliegman <kliegs@...omium.org>

Setting this bit to 0 causes the system to wait until suspended
to use the wakeup masks.  With it being set high previously,
masked interrupts were being received and processed before the
EINT_WAKEUP_MASK was configured.
