Framework 13 AMD Support on Linux

[afzalarsalan]

I've noticed that trying this tool on Linux runs into the issue where /dev/cros_ec doesn't seem to exist on the latest kernel. I wanted to know if there was any blockers or action items that would enable this program's functionality to work on Linux
