The 8254x apparently doesn't respond well to I/O accesses at 0. Do not
attempt to map the I/O BAR if it is 0. This will have the side-effect
of causing the wm_reset() routine to fall back to memory BAR accesses
for those chips on which it would attempt I/O BAR accesses for the reset.
Also update the comments about why we attempt the I/O BAR accesses for
the reset in favor of the memory BAR accesses.
