The WiFi/Bluetooth SDIO chip is attached to SDMMC3 on AV96, describe it in DT to make it available. Remove WiFi LED and turn it into a regulator, because it is a GPIO controlling the WL_REG_ON input of the WiFi chip. The LED is just an indicator connected to the same line, but not the primary function.
