lenovo: add config ONBOARD_VGA_IS_PRIMARY
Fix for the T4xx and T5xx series.
It does not apply to X2xx/X6x series as those have only
one GPU, which is always connected to the display.
The T6x series needs special care not handled with this patch.
Without ONBOARD_VGA_IS_PRIMARY the onboard GPU would be
deactivated in case a dedicated GPU is found and active,
leaving the system without a working display.
