pieeprom-2025-09-22: 2711: Add LZ4 decompressor (latest)

* Add LZ4 decompressor
  LZ4 gives a better compression ratio than the previously used CK compress. The bootloader can now decompress both LZ4 compressed files and CK compressed files.
* rpifwcrypto: Add GET_CRYPTO_PRIVATE_KEY mailbox API
  For provisioning, add a new mailbox API which returns the private key
  in DER format. The API will return an error if the key-status for
  the specified key is LOCKED.
* config: Add support for board_attributes in conditional expressions
  Add support for the board-attributes row in config.txt conditional
  expressions. This can be used to change boot behavior for
  Compute Module Lite / No-WiFi etc.
* board_info: Log the OTP board revision at startup
  Log the board revision plus the raw OTP value at startup.
