[Test] Verified on some new Dell machines and confirmed it works. [Fix] Write a new driver to handle this task. [Regression Potential] Low, it's a new driver for new interface. [Misc] Upstream maintainer ask use to re-implement this driver by the new interface, serdev, but serdev seems doesn't work with ACPI, so submit this driver as Ubuntu sauce patch for now. I'll try re-write it when I'm available.
