mb/lenovo/t520: Add Dual Graphics CMOS support
Adds the CMOS option for Dual Graphics, as is present in more Lenovo models already. Enabling this option ensures that the NVIDIA GPU is powered. More PCI devices can be observed when activating this setting. It was verified on a W520, also by loading a VGA option ROM and achieving a working Dual Graphics system. The CMOS default has been kept to 'Integrated Only', as the usage of Dual Graphics requires an option ROM and drains the battery more quickly.
