libpayload: sync arch/arm/cache.c with coreboot

There was a recent patch by Deepa Dinamani applied to coreboot's
    cache.c which fixed a bug that occurred when icache is on but dcache
    is off ("arch: armv7: Fix cache sync instructions."). Although this
    bug is not likely to be encountered by the time libpayload is run,
    it's worth applying it to keep things in sync.

BUG=none
    BRANCH=none
    TEST=n/a since we have icache and dcache enabled on all ARM platforms
    when libpayload is run.
