[PULL][SRU Bionic] Parse the ACPI PPTT table

[dann frazier]

This PR comprises all clean cherry-picks from upstream & linux-next,
except for one which required very minor backporting.

I've tested on a HiSilicon D06 arm64 server and a Qualcomm QDF2400,
which both provides a PPTT table. I also regression tested on a POWER9
system, since some of the changes are to device-tree code, and that's
the other Ubuntu architecture that supports device-tree. Details,
including a patch-by-patch regression risk analysis are in the bug.
