documentation: Format button_dev as a pointer.

Browse source 
The docs on creating an input device driver have an example in which
button_dev is a pointer to an input_dev struct. However, in two code
snippets below, button_dev is used as if it is not a pointer. Make these
occurrences of button_dev reflect that it is a pointer.
