nb/intel/pineview: Native VGA init (CRT)

Browse Source 
VGA grub console works but display wobbles left/right

drm/i915 driver reports one error:
- [drm:i915_irq_handler] *ERROR* pipe A underrun
- Monitor does not display 1920x1080 after modeset
- Other resolutions look out of sync

Cause: suspect single bug in raminit (chipset init)
