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.

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, it shows the Tianocore logo/setup menu and the desktop on
the display.
