exynos5420: 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.
