Add support for AlderLake CPUs

[Colin Ian King]

[Impact]

 * Support thermald on AlderLake CPUs.

[Test Plan]

 * Use a machine with a AlderLake CPUs
 * systemctl status thermald
 * Status of thermald should be `running`

[Where problems could occur]

 * This change is to support Jasper Lake in thermald, which won't impact other hardware because the changes match on the CPU model ID.

[Other Info]

Supported added with:

Hello Colin, or anyone else affected,

Accepted thermald into focal-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/thermald/1.9.1-1ubuntu0.6 in a few hours, and then in the -proposed repository.

Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested, what testing has been performed on the package and change the tag from verification-needed-focal to verification-done-focal. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed-focal. In either case, without details of your testing we will not be able to proceed.

Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance for helping!

N.B. The updated package will be released to -updates after the bug(s) fixed by this package have been verified and the package has been in -proposed for a minimum of 7 days.

The verification of the Stable Release Update for thermald has completed successfully and the package is now being released to -updates. Subsequently, the Ubuntu Stable Release Updates Team is being unsubscribed and will not receive messages about this bug report. In the event that you encounter a regression using the package from -updates please report a new bug using ubuntu-bug and tag the bug report regression-update so we can easily find any regressions.

Exercised hirsute thermald 2.4.3-1ubuntu3 for 3 hours - no observable regression under varying CPU loads that cycled the temperature between 65 and TjMax. Looks good to me.
