Kernel improvements (#468)

* **New Features**
  * Plugin-style modules for platforms and devices with start/stop lifecycle and a runtime-consumable device tree array.

* **Refactor**
  * Consolidated initialization into a kernel/module startup flow.
  * Generated devicetree artifacts moved to the build Generated directory.

* **Changes**
  * Removed legacy no-op registration hooks and I2C lock/unlock wrappers.
  * Driver ownership and private state moved to explicit module/owner model.
  * Added ERROR_NOT_ALLOWED error code.
