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.
