The new code had a bug in that it only ever enabled the first monitor
rather than all usable ones. Fix this by removing the erroronuous break.
Also clarify the comment a bit that the current solution is not really
ideal as it may result in invalid configurations (i.e. we enable more
outputs than are possible with the number of available CRTCs).

Fixes #418
