[Contributors wanted!] Intel DTT

I would like to add the DTT state in _CoreFreq_ Technologies We have specs at Intel for [gen. 12](https://edc.intel.com/content/www/us/en/design/publications/12th-generation-core-processor-datasheet-volume-2-of-2/d4-f0-dynamic-tuning-technology-registers-registers/) and we just need to probe registers at the PCI device BDF `0x0:0x4:0x0` for the technology availability and, to my understanding, offset `0x54` for its enablement state I do not have such hardware. Let me know if you want to contribute ; mostly with testings ? ---- _Originally posted by @cyring in https://github.com/cyring/CoreFreq/discussions/568_
