b53: fix mmap register read/writes > 32 bit
For bcm63xx integrated switches, broadcom changed the data endianess
to match the system endianess. But this only applies to within one word,
which causes 48/64 bit values to be still split into their "litte endian"
groups.
E.g. 48 bit values (with 5 being the most significant byte) aligned
0x00 ..01 or 0123
0x04 2345 45..
will become
0x00 ..10 resp. 3210
0x04 5432 54..
Likewise for 64 bit values.
