config: fix GPUDevice fail when AutoAddGPU off + BusID 

This fix is for the following xorg.conf can work:

Section "ServerFlags"
        Option  "AutoAddGPU" "off"
EndSection

Section "Device"
        Identifier "Amd"
        Driver "ati"
        BusID "PCI:1:0:0"
EndSection

Section "Device"
        Identifier "Intel"
        Driver "modesetting"
        BusID "pci:0:2:0"
EndSection

Section "Screen"
        Identifier "Screen0"
        Device "Intel"
        GPUDevice "Amd"
EndSection

Without AutoAddGPU off, modesetting DDX will also be loaded
for GPUDevice.
