Call out usability on big-endian machines specifically here.

I added this to v3.14/gpio branch of my tree (with modifications I
mentioned above).

I dont think there are dependencies for this particular patch though
(applies and builds nicely on latest Linus  T's tree). Even then, there
are too many GPIO patches floating around and I think it is better for
me to collect them for a while and if there really are no platform code
dependencies overall, I can probably hand that branch off to Linus W. We
will see.

Thanks,
