Another vga_switcheroo cleanup. Maintainers, is it okay to include the one-line change of each driver in here or do you want that split into separate patches?

...ng external Thunderbolt GPUs with vga_switcheroo: Dave Airlie designed vga_switcheroo to register GPUs unconditionally. So if a desktop box has multiple GPUs, vga_switcheroo will see more than one discrete GPU but that's not a problem because on desktop boxes no handler is registered and thus vga_switcheroo_enable() is never called. Hybrid graphics laptops on the other hand do register a handler, but are assumed to never register more than one discrete GPU. However once a Thunderbolt eGPU is attached to a hybrid graphics laptop, that assumption is no longer true and things go south when vga_switcheroo runti...

Enable GPU switching on the pre-retina MacBook Pro (2008 - 2013), v5. The main obstacle on these machines is that the panel mode in VBIOS is bogus. Fortunately gmux can switch DDC independently from the display, thereby allowing the inactive GPU to probe the panel's EDID. In short, vga_switcheroo and apple-gmux are amended with hooks to switch DDC, DRM core is amended with a
