Bug Description
[Impact]
New Dell AIO platforms requires a driver that can communicate with the scalar IC FW through UART interface to get and set the brightness level.
[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.

raise this issue to critical, because it's a subtask of COL 3.0
<alextu> AceLan, so, LP: #1727235, is not upstream yet, right ? it's a blocker of COL 3.0
