Damien George 52a78e6965 drivers/cyw43: Fix cyw43_deinit so it can be called many times in a row. 
This makes sure deinit() can be called on the interface many times without
error, and that the state of the driver is fully reset.

Fixes issue #7493.

CYW43xx WiFi SoC driver

This is a driver for the CYW43xx WiFi SoC.

There are four layers to the driver:

  1. SDIO bus interface, provided by the host device/system.

  2. Low-level CYW43xx interface, managing the bus, control messages, Ethernet frames and asynchronous events. Includes download of SoC firmware. The header file cyw43_ll.h defines the interface to this layer.

  3. Mid-level CYW43xx control, to control and set WiFi parameters and manage events. See cyw43_ctrl.c.

  4. TCP/IP bindings to lwIP. See cyw43_lwip.c.
