Fix PocketBeagle 2 support: correct DT compatible string and black formatting

- Fix chip.py: The device-tree compatible string was incorrectly
  concatenated as 'beagle,am62-pocketbeagle2ti,am625' (two DT entries
  mashed together). Changed to 'beagle,am62-pocketbeagle2' which is
  the actual compatible value from the PocketBeagle 2 device tree.
- Fix boards.py: Remove stray blank line inside BEAGLEBONE tuple that
  caused black formatting CI failure.
- Clean up board.py comment: The special-case EEPROM check is the
  correct approach for new-format Beagle boards (like BeaglePlay),
  so replaced the uncertain comment with an explanatory one.
