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.
