drm/i915: PSR HSW/BDW: Fix inverted logic at sink main_link_active bit. 

We have only two possible states with so many names and combinations that
might be confusing.

1 - Main link active / enabled / stand by / on
2 - Main link disabled / off / full off

Let's start organizing it by fixing a inverted logic when setting the sink bit.
