Describe the Ethernet LEDs for the Raspberry Pi 4 model B board as well
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.

The Ethernet PHY LEDs are numbered in the PHY package/pin list from LED1
through LED4, however their address within the LED registers function
selector is 0-indexed.

Signed-off-by: Florian Fainelli <florian.fainelli@broadcom.com>

Changes in v3:

- explain LED numbering and add comments
- rename individual LED DT nodes to led@<N>

Changes in v2:

- added function = LED_FUNCTION_LAN
- rebased against latest tree
