Steve Boylan 37e39dee58 drivers: wifi: infineon: Add SPI support to AIROC driver
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
