exynos5250: Clear the framebuffer before making it uncacheable.

If we clear the framebuffer and then flush it back to memory using cache
    operations, the writes are going to be full cachelines at a time. If we make
    it uncacheable first, the writes will be serialized writes of whatever sized
    chunks memset uses, probably 4 bytes or less.
