[POWERPC] Use const qualifiers for prom parsing utilites
The of_bus callbacks map and get_flags can be constified, as they don't alter the range or addr arguments. of_dump_addr and of_read_addr can also be constified. Built for 32- and 64-bit powerpc Signed-off-by: Jeremy Kerr <jk@ozlabs.org> Signed-off-by: Paul Mackerras <paulus@samba.org>
