GPIO refactored (#495)

* **Refactor**
  * GPIO subsystem moved to a descriptor-based model for per-pin ownership and runtime pin management; many platform drivers now acquire/release descriptors.
  * Device trees and drivers now use GPIO phandle-style pin specifications across all boards and all drivers.

* **Behavior**
  * Device list now encodes per-device status (ok/disabled); boot will skip disabled devices accordingly.

* **Deprecation**
  * Legacy GPIO HAL marked deprecated and replaced with descriptor-based interfaces.

* **Chores**
  * Bindings and platform configs updated to the new GPIO pin-spec format.
