I have a feeling we should just use the normal IS_MOBILE() thing
here. But untangling that mess might be a bit of work.

This is clearly just IS_MOBILE().
Or we just keep the current pci id checks. Frankly I see no benefit in
abstracting these few exceptions.

Why is AML_ULX different from normal ULX?

God that PORTF thing is ugly. I would suggest we just add port_mask
or something along those lines into the device info.
Then we could perhaps even avoid adding more and more branches to
intel_setup_outputs(). Although I'm not sure we need anything for that
since we'll look at the VBT anyway (which *maybe* doesn't advertize
ports that aren't present?).
