platform/x86: Add driver to force WMI Thunderbolt controller power status
Current implementations of Intel Thunderbolt controllers will go into a low power mode when not in use. Many machines containing these controllers also have a GPIO wired up that can force the controller awake. This is offered via a ACPI-WMI interface intended to be manipulated by a userspace utility. This mechanism is provided by Intel to OEMs to include in BIOS. It uses an industry wide GUID that is populated in a separate _WDG entry with no binary MOF. This interface allows software such as fwupd to wake up thunderbolt controllers to query the firmware version or flash new firmware.
