Paul Menzel b586640141 intelfb: fix a bug when changing video timing 
When changing video timing dynamically via fbset the screen sporadically
is rendered black.

With the attached fix which disables VCO prior to timing register change
the problem disappears.

I had a look at the Xserver register setup code. Here the VCO is
disabled in the same way [1].

This patch is taken from vga-sync-field version 0.0.11 [2][3].
