commonlib/device_tree: fix 64-bit misaligned member access

On RISC-V (or any other platform), pointers to 64-bit values in the
device tree (spanning 2 cells) are not guaranteed to be aligned to a
64-bit boundary, which can cause a load access fault on some
platforms (see [0]). This is observed with the default Spike device
tree. Thus, perform two 32-bit loads instead.
