lenovo/haswell: enable ONBOARD_VGA_IS_PRIMARY
Haswell ThinkPads have Nvidia Optimus wired in on some models.
With recent coreboot changes, legacy VGA decode is now disabled
on the iGPU, and the iGPU itself is disabled, when a dGPU is
present. This is a problem on Optimus laptops, because it means
that the Intel GPU would be effectively disabled, when it is the
one that has to handle the framebuffer.
On these boards, you can enable ONBOARD_VGA_IS_PRIMARY so that
coreboot does not disable the iGPU. This is because on Optimus
laptops, the Nvidia GPU is only used for offloaded rendering.
Enable ONBOARD_VGA_IS_PRIMARY by default on these boards.
