Title: Update directive.ngdoc

Spent a far too much time trawling through the internet for information on why there is a ctrl argument in validators when, according to documentation, the link option only takes three arguments. The information is available further down the page but with the rather axiomatic specification in this part I saw no reason to look for it there.
