mainboard/lenovo: add cmos layout for hybrid graphics
Add cmos layout vga_primary_is_peg and vga_secondary_powersave.
vga_secondary_powersave defaults to true and must remain true !
Using two GPUs at the same time isn't supported at time by the
hybrid graphics driver and will result in black screen.
Toggling vga_primary_is_peg allow switching between
integrated and dedicated GPU using nvramtool.
Tested on Lenovo T520 using Nvidia NVS 5200m.
