DTB is encoded in big endian. When we retrieve property values, we need to use fdt32_to_cpu (aka be32_to_cpu) for endian conversion. This is a bit error-prone, but sparse is useful to detect endian mismatch.
We need to use (fdt32_t *) instead of (u32 *) for a pointer of a property value. Otherwise sparse warns "cast to restricted __be32".
