IB/ipath: Add flag and handling for chips with swapped register bug
The 6110 had a bug that caused some registers to be swapped; it was
fixed for the 7220 (and didn't affect the 6120 because it had fewer
registers). This adds a flag and related code to handle that, and
includes some minor cleanups in the same area.
