ARM: SAMSUNG: fix to support for missing cpu specific map_io
Since commit 7ed76e08 (ARM: EXYNOS: Fix low level debug support) map_io() is not needed for exynos5440 so need to fix to lookup cpu which using map_io(). Without this, kernel boot log complains 'CPU EXYNOS5440 support not enabled' on exynos5440 and panic(). Signed-off-by: Kukjin Kim <kgene.kim@samsung.com>
