This patch introduces the core layer of the nxpwifi driver, which provides the foundational logic and infrastructure for managing the wireless adapter. Highlights: - Implements adapter registration, initialization, and teardown - Defines the main driver loop for handling TX/RX, command, and event flows - Adds firmware download and wakeup handling logic - Introduces power management, workqueue, and interrupt handling - Provides debug and device dump support for diagnostics - Defines core data structures and interfaces in main.h - Establishes the interface abstraction via nxpwifi_if_ops for bus drivers This core layer enables the bus-specific driver to instantiate and operate the Wi-Fi device through a well-defined callback interface.
