Fix chip detection failure on Alpine Linux and other non-standard distros

Three fixes in chip.py:

1. Add early device-tree check for Broadcom BCM chips. Previously,
   BCM detection relied solely on /proc/cpuinfo Hardware field, which
   is absent on aarch64 Alpine Linux (and potentially other distros).
   The new check matches 'brcm,bcm2' in /proc/device-tree/compatible,
   which is present on all Raspberry Pi boards regardless of distro.

2. Guard against NoneType crash when compatible is None. If both
   /proc/cpuinfo Hardware and /proc/device-tree/compatible are
   unavailable, compatible.split() would raise AttributeError,
   which gets silently swallowed by __getattr__ and surfaces as
   a confusing bare AttributeError.

3. Include attribute name in __getattr__ AttributeError for better
   debugging.

Fixes #342

Bump max-module-lines from 1000 to 2000

board.py is already at 1461 lines and growing as new boards are added.
The 1000-line limit causes build failures when adding new board support.

Bumping to 2000 provides headroom until the board detection logic can be
refactored into a data-driven approach (similar to Adafruit_Blinka#1040).

Fixes #296

Fix Orange Pi detection on non-Armbian systems (Debian)

Add _orange_pi_id() to H616 and H6 chip detection paths so that
Orange Pi boards are detected via device-tree model strings on
non-Armbian OS distributions (e.g. Debian).

Expand _orange_pi_id() to handle Orange Pi Zero 2, Zero 3, Zero 2W
(with space variant), and 3 LTS model strings from /proc/device-tree/model.

Fixes #285

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

- 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.

Update Read the Docs configuration for latest Ubuntu and Python

Note that the Python choice is just for RTD builds, not in general.
