This isn't at all descriptive, it'd be better to have a capability bit
for the various multi-line data modes (or possibly individual bits for
them, though board setup will stop us using things that aren't supported
in a given design anyway so it's a bit redundant) - that'd be a lot
clearer and avoid confusion further down the line when some other
feature gets added.
