Thomas Zimmermann 70c3881eed drm/mgag200: Set/clear <syncrst> field in display enable/disable helpers 
Modifying the <syncrst> field in mgag200_{enable,disable}_display()
makes the code more readable. Also clear the <asyncrst> field to enable
the display. The other bits in SEQ0 are unused, so no functional changes
are made.
