boards/esp32s3-xiao: wire up esp_openeth_initialize()
esp32s3-devkit, esp32s3-ws-lcd128, lckfb-szpi-esp32s3 and esp32-devkitc
all call esp_openeth_initialize() from their bring-up to register the
openeth MAC (the NIC QEMU's esp32s3 machine provides); esp32s3-xiao
never did, so CONFIG_ESP32S3_OPENETH built but no wlan/eth netdev ever
registered under QEMU -- same shape of gap as the IMU, SD, console,
Wi-Fi and SPI-flash wiring already fixed for this board.
Confirmed under QEMU's esp32s3 machine, combined with the esp_openeth
RX-interrupt fix (merged in 88c8623cedb): the netdev registers and the
guest genuinely sends and receives.
