nehalem native gfx init: Adjust state to be compatible with OPROM.
My main payload is GRUB and I load SeaBIOS as secondary payload when for some
reason I want to boot windows. In this scenario SeaBIOS runs VGA oprom
(SeaVGABIOS is not good enough with intel gfx). VGA oprom expects either
completely uninited gfx or some special state in gmbus and software scratch
registers. Provide this state.
The only alternative without this patch for such usecase is to use oprom and
I'd like to avoid doing so when going my main boot path to GNU/Linux.
