exynos5420: Don't map low addresses that lead nowhere

I just spent half a day (including the time to implement a stack dumper)
    to figure out that I am reading from a NULL pointer. A problem this
    simple should be more easy to catch. Let's mark the address range below
    SRAM as uncached so that the MMU can yell at you right away for being
    the bad programmer you are when you access a NULL pointer.
