Default pins for A4988 do not match Wiki

Hi,

The pins shown in the graphics and tables on the following page do not match the defaults in the config files.

While builders should double check the config file, I did to make sure the options were enabled, it would be good if these matched by default so that people wouldn't get confused like I did when it wouldn't work.
