This isn't necessary anymore, you are able to specificy everything you
need through the platform data these days (this is true for smc91x as
well as smc911x). So you can reduce the following:

to:

static struct smc91x_platdata smc91x_info = {
	.flags = SMC91X_USE_16BIT,
};

And then pass that in under the platform device. We already do that today
for migor, se7722, etc.
