apple-gmux: Add helper for presence detect
Centralize gmux' ACPI HID in a header file and add apple_gmux_present(). This can be used by other drivers to activate quirks specific to dual GPU MacBook Pros & Mac Pros. The alternative would be to hardcode DMI or PCI IDs and amend them whenever Apple introduces a new machine.
