So far we've got one condition when DRM drivers need to defer probing on a dual GPU system and it's coded separately into each of the relevant drivers. As suggested by Daniel Vetter, deduplicate that code in the drivers and move it to a new vga_switcheroo helper. This yields better encapsulation of concepts and lets us add further checks in a central place. (The existing check pertains to
