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).
