This quirk is used so far used on:
- LG G7 ThinQ
- Xiaomi Poco F1

I'm resending it after ~ 4 years since initial send due to Snapdragon
845 being one of best supported platform for mobile phones running
Linux, so it would be shame to not have shiny support.

Original thread:

I tried the embedding the information inside the firmware, but the
information is required *before* loading the firmware itself.
