The 'struct nvmem_config' has a stride attribute that specifies the needed alignment for accesses into the nvmem. This is used in nvmem_cell_info_to_nvmem_cell() but not in the sysfs read/write functions. If the alignment is important in one place it's important everywhere, so let's add enforcement. For now we'll consider it totally invalid to access with the wrong alignment. We could relax this in the read case where we could just read some extra bytes and throw them away. Relaxing it in the write case seems harder (and less safe?) since we'd have to read some data first and then write it back. To keep it symmetric we'll just disallow it in both cases.
