Added support for SPI in 4-wire and 3-wire configurations to the Infineon AIROC WiFi driver (drivers/wifi/infineon). Review changes: Move DT_DRV_COMPAT to common header file Correct board-specific preprocessor lines Removed AIROC_MAP_COUNTRY_CODE Move Pico W configuration details to devicetree Use pinctrl to manage shared data/interrupt GPIO Clean up bus selection in Kconfig.airoc Make SDIO and SPI bus struct independent Replace LOG_DBG with LOG_ERR Remove functionally duplicate operation Remove spurious Kconfig option Minor cleanup in CMakeLists.txt Signed-off-by: Steve Boylan <stephen.boylan@beechwoods.com>
