mb/system76: Set PrimaryDisplay to hybrid graphics

Use the FSP option for (muxless) hybrid graphics. Internally it ends up
setting PrimaryDisplay to iGFX, but does some extra configuration for
the dGPU.

Only galp5 is left as setting PrimaryDisplay to iGFX as the dGPU was
optional for the model and I don't know what effect it would have to set
it to hybrid for those.
