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.
