M4A785T-M: Add support for external GFX.
This commit enables the external graphics card.
In order to work, the internal graphic card has to be
disabled, that is done in src/device/device.c through:
which calls the RS780 disable operation introduced in the following
commit: "rs780: add .disable pcie_ops"
This commit was tested with and without the following card:
02:00.0 VGA compatible controller: nVidia Corporation GT218 [GeForce 210] (rev a2)
Thanks Aladyshev for the pointer(in the #coreboot IRC channel on Freenode servers):
Dec 20 19:43:32 <Aladyshev> If you list your internal card in devicetree.cb,
coreboot will distinguish external and internal VGA and choose external one
