Prevent unaligned access when addr_cells != size_cells.

This feels wrong, you should be using OF_getencprop to read the data.

For starters I agree with Andy's comment. I'm having a hard time coming up with a reason why OF_getencprop() wouldn't work and fdt_data_get() would have to be used instead.

That said, this is wrong; it only works on little-endian systems. The correct approach would be to do what OF_getencprop() does: ignore the low-quality fdtNN_to_cpu() code and just use be32toh() on each cell individually.
