I'm essentially questioning about the point of the patch.  It intends
to save a little space for imx6q build without caring about imx3 and
imx5.  That said, when imx6q is excluded from the build, we are still
wasting those space.  That's why I'm not so excited about the patch.

Looking at current users of this definition, you will find all of them
are defining a number bigger than 256 for extending the maximum number.
It might be a sign that having a gpio array which is a little bigger
than necessary is not a concern on machines today.
