Extend existing X1 Elite support with the modules needed to bring up the Lenovo Thinkpad T14s Gen6. Since most of the firmware has been upstreamed to linux-firmware, the yoinker is not required. Tested with full disk encryption, unl0kr works as expected.
Things which now work:
Bluetooth
CPU frequency scalling
external display untested, tested with a thinkpad usb c hub and a noname usb hub
As for functionality, the main pain points are:
Audio (Profile, can play sounds, but will overheat the speakers)
USB OTG - the ports are dual role capable but all forced to host mode for some reason. If you do change the first port to peripheral then you'll get the normal USB network device show up if you attach it to your PC.
