ARM: EXYNOS: Fix the sequence of secondary CPU boot for Exynos3250
This patch set AUTOWAKEUP_EN bit to ARM_CORE_CONFIGURATION register
because Exynos3250 removes WFE in secure mode so that turn on automatically
after setting CORE_LOCAL_PWR_EN. Also, This patch use dbs_sev() macro
to guarantee the data synchronization of command instead of IPI_WAKEUP
because Exynos3250 don't have WFE mode in secue mode.
