ARM: EXYNOS: Fixups for big-endian operation
If the kernel is built big endian, then using the __raw read and write IO accessors is not going to work as they end up writing big-endian data to little-endian IO registers. Fix this by using the readl and writel relaxed versions which ensure little endian IO.
