of/address: use proper endianess in get_flags

Browse Source 
This patch changes u32 to __be32 for all "ranges", "prop" and "addr" and
such. Those variables are pointing to the device tree which contains
integers in big endian format.

Most functions are doing it right because of_read_number() is doing the
right thing for them. of_bus_isa_get_flags(), of_bus_pci_get_flags() and
of_bus_isa_map() were accessing the data directly and were doing it wrong.
