rp2: Define cyw43 pins.

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.
