* Honor ACPI _CRT for processor thermal zone (LP: #1803360)
There are some new fanless platforms use DPTF's virtual sensor
instead of INT340X devices. Because of that, the _PSV is no
longer in use, at least not directly, hence its value may set
higher then _CRT. To a fanless system that means no cooling
device gets activated before _CRT, so the system will be
considered overheated by Linux kernel, and gets shutdown by the
kernel. Upstream fixes:
- 7af3eef07dc7 Ignore _TRT and B0D4 device if passive 1 UUID not present (prerequisite)
- 97976782dd26 Honor ACPI _CRT for processor thermal zone
