rtas_call() accepts and returns values in CPU endianness. The ddw_query_response and ddw_create_response structs members are defined and treated as BE but as they are passed to rtas_call() as (u32 *) and they get byteswapped automatically, the data is CPU-endian. This fixes ddw_query_response and ddw_create_response definitions and use. of_read_number() is designed to work with device tree cells - it assumes the input is big-endian and returns data in CPU-endian. However due to the ddw_create_response struct fix, create.addr_hi/lo are already CPU-endian so do not byteswap them. ddw_avail is a pointer to the "ibm,ddw-applicable" property which contains 3 cells which are big-endian as it is a device tree. rtas_call() accepts a RTAS token in CPU-endian. This makes use of of_property_read_u32_array to byte swap and avoid the need for a number of be32_to_cpu calls.
