Note that we generally try to avoid using bitfields for hardware
descriptions and instead use masking/shifting, possibly hidden in
macros. The portability argument for that doesn't really apply
here as the code is obviously MIPS/big endian specific, but I think
it generally is a good example and more readable as well.
