exynos: Set up caching in the bootblock.

This improves firmware boot time substantially. Because cbmem isn't available
    yet, we need to allocate some space in sram for the ttb. Doing cache
    initialization in the bootblock means we can implement this once per CPU
    instead of once per mainboard.

exynos5420: flush caches and disable MMU in resume path

This patch flushes the caches and disables the MMU before resuming.

c32b9b3 ("Set up caching in the bootblock.") had a bug where the
    dcache and MMU remained enabled in the resume path. This caused
    the machine to hang on resume. However, other bugs were preventing
    us from testing this properly earlier on so it went unnoticed until
    now.
