[SRU] [Bionic/Unstable] [PATCH v2 0/4] Enable AMD PCIe MP2 for AMDI0011

[Kai-Heng Feng]

BugLink: https://bugs.launchpad.net/bugs/1773940

[Impact]
Touchpad doesn't work on Latitude 5495.

[Test]
I can confirm the driver from AMD works.
With patch 2/3, no issues found so far.

[Fix]
The touchpad connects to AMDI0011, which doesn't have any driver until
now.

The original plan is to use an upstream version for this driver, but the
review process took longer than anticipated, and the driver is really in
need as the Latitude 5495 is about to hit the market.  I'll replace this
patch set with upstream version once it's in mainline.

v2: Fix build for architectures don't support ACPI.

[Regression Potential]
Low. It's a new driver, shouldn't affect any other device.
