Describe the Ethernet LEDs for the Raspberry Pi 4 model B board as wellReviewed-by: Stefan Wahren <wahrenst@xxxxxxx>
as the Raspberry Pi 4 CM board. The Raspberry Pi 400 board does not
include RJ45 connector LEDs so the 'leds' node is deleted accordingly.

through LED4, however their address within the LED registers function
selector is 0-indexed.
