exynos5250: Don't disable and re-enable the MMU when uncaching the framebuffer.

At one time it seemed to be necessary to disable and then re-enable the MMU
    when setting the framebuffer to be uncache-able due to bugs in the MMU
    management code. Since those bugs have been fixed, this is no longer
    necessary.
