thermald not works on intel GeminiLake

[Alex Tu]

After the patch landed by "LP: #1851506 Add GeminiLake support on Intel int340x thermal device"

The thermal zone "TCPU" is corretly created, but thermald still not work as expected on bionic so system will shutdown by cpu stress test.

But thermald 1.9 works well with patched kernel, so it might some patches needed for thermald 1.7 on bionic.

just verified this case on intel glk , platform pci subsystem ID = 08AF with 2 ways to heating CPU:
 - $ stress -c 20
 - $ sudo stress-ng --ignite-cpu --cpu 4

with thermald 1.7.0-5ubuntu5 + kernel 4.15.0-1065-oem , the thermald looks work well and the system was not shut down by overheating.

refer to the attached log from thermald with `--loglevel=debug`.

by monitoring sensors in /sys/class/thermal/, the temperature is keep closing to critical (95 degree), but thermald will always cool it on time.

So, I will mark this issue as invalid.
