Well, then we should probably use the existing macros
(include/asm/byteorder.h), but the downside is that this will grow the
diffs between the remaining ohci drivers and the generic one which will
make merging them more work. I'd prefer to leave cosmetic stuff for now,
until the other drivers are merged.
