The cyw43 pins used to be hardcoded and `CYW43_PIN_WL_HOST_WAKE` and `CYW43_PIN_WL_REG_ON` were in the `pico_w.h` board header. This has been changed so the board header just defines the "default version of the pins, e.g. `CYW43_DEFAULT_PIN_WL_HOST_WAKE`, `CYW43_DEFAULT_PIN_WL_REG_ON` etc. Set the pin values in `cyw43_configport.`h so `cyw43-driver` sees them and allow them to be changed at runtime (dynamic) if required.
