Ville Syrjälä e1553faa90 drm/i915: Fix VGA_DISP_DISABLE check ... The VGACNTRL register contains a bunch of other stuff besides the VGA_DISP_DISABLE bit. When we write the register we always set those other bits to zero, so normally the current check would work. However on HSW disabling and re-enabling the power well will reset the VGACNTRL register to its default value, which has several of the other bits set as well. So only look at the VGA_DISP_DISABLE bit when checking whether the VGA plane needs re-disabling.
