You can ignore the alignment warning, it's been decided that Intel
driver/firmware/hw will not work properly on platforms that cannot do
unaligned loads efficiently. I've tried sending a patch to add
CONFIG_HAVE_EFFICIENT_ALIGNED_ACCESS or something like that so that we
can fix it up if that is unset or make the driver depend on it, but it
hasn't stuck so far, so for now, ignore the warning and don't try to use
Intel wireless hw on platforms that don't like unaligned loads.
