google/buddy: fix Windows ACPI error with WLAN
Buddy's WLAN ACPI code was equivalent to, but formatted differently from the other auron variants. Since only differnce is root port used, have buddy use common WLAN ACPI and use preprocessor guards to set the root port correctly. Test: build/boot Buddy, verify Windows 10 boots without ACPI BIOS ERROR.
