Subject: [PATCH v6 18/22] wifi: nxpwifi: add core driver implementation
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.
