of: assume big-endian properties, adding conversions where necessary
Properties in the device tree are specified as big-endian. At present, the only platforms to support device trees are also big-endian, so we've been acessing the properties as raw values. We'd like to add device tree support to little-endian platforms too, so add endian conversion to the sites where we access property values in the common of code. Compiled on powerpc (ppc44x_defconfig & ppc64_defconfig) and arm (fdt support only for now).
