libpayload: Let GDB stub read/write memory with aligned MMIO words

Looks like we got our first SoC that actually insists on using
    word-sized accesses for its MMIO registers with the Rk3288. This patch
    changes the GDB command handler for reading and writing memory to always
    perform word-sized accesses. This isn't really perfect since the remote
    GDB interface is just not really meant to interact with MMIO (e.g. you
    shouldn't use this on something with read side effects), but for most
    of our purposes it should be good enough.

BUG=chrome-os-partner:18390
    TEST=Remote GDB works on Veyron even when writing MMIO registers.
