Support R/W of OTP fuses on BCM2711 processors

What kind of new feature are you looking for?

• Hardware: Read/Write OTP fuses on the BCM2711 and possibly other Raspberry Pi processors

Do you plan to:

• Contribute an initial driver: Yes
• Write unit tests: Yes, with the caveat that the test for writing OTP fuses is destructive
• Update https://github.com/periph/cmd to use the new functionality: No, the official vcgencmd already handles this use case

Description of the problem This library lacks the ability to read and write OTP fuses on BCM2711 processors. Extending videocore/videocore.go to to interface with the GPU to read/write the OTP fuses seems to be the correct place to add this feature.

Sounds great!
