soc/{apl,glk}: Allow to select the primary graphics device
Allow to select the primary graphics device between the IGD and the
external PCIe GPU depending on the ONBOARD_VGA_IS_PRIMARY config.
The option sets the priority only. This means that if a high priority
is set for an external PCI device and it is not connected/not enabled,
then the device with a lower priority will be used, in our case it is
IGD.
TEST = Set PRIMARY_PCI and boot Linux on the Kontron mAL10 [1] with
the miniPCIe video adapter on the Silicon Motion SM750 controller. As
a result, the display connected to an external GPU device shows the
Tianocore logo + setup menu and the desktop.
