I just noticed in the datasheet that memory_dev needs to be inverted,
otherwise we read dev0 instead of dev1 and vice versa. This also needs
to be corrected in the T20 EMC driver. It's not really a problem since
both memory chips usually are equal, nevertheless I'll fix it in v2
after we will decide on whether this code needs to be shared or not.
