Make TPM accessible on Compulab imx8

I created an issue on github to add support for TPM on Compulab IMX8. Looking at this issue and its PR it seems that in only takes 9 Lines of yocto config to get that running. Can somebody look into that?

Hi, I have opened a PR (linux-compulab: Add TPM support by alexgg · Pull Request #323 · balena-os/balena-iot-gate-imx8 · GitHub) - once it’s built we will do some basic checks.

I don’t think we have automated tests for this device type - we will have to add it to the automation so it can be released as we no longer have manual test processes.
