Tim Gover 6c2e2d6833 pieeprom-2025-03-19: 2712: Log the fan speed at boot (latest) ...

* Log the fan speed at boot
  Record the fan RPM (and the maximum seen) during boot, so that it is
  accessible using "sudo vclog -m".
  See: https://github.com/raspberrypi/rpi-eeprom/issues/678
* Add current_supply to HAT+ support
  Refactor the HAT library to make it more self-contained, and combine
  the I2C address detection and the reading of the EEPROM contents.
  Use it to allow the earlier boot stages to check for a current_supply
  setting in the EEPROM of a normal (non-stackable) HAT+.
