dt-bindings: leds: Add LED_FUNCTION_SPEED_* for link speed on LAN/WAN

Browse Source 
Add LED_FUNCTION_SPEED_LAN and LED_FUNCTION_SPEED_WAN for LEDs that
indicate link speed of ethernet ports on LAN/WAN. This is useful to
distinguish those LEDs from LEDs that indicate link status (up/down).

example:

Fortinet FortiGate 30E/50E have LEDs that indicate link speed on each
of the ethernet ports in addition to LEDs that indicate link status
(up/down).

- 1000 Mbps: green:speed-(lan|wan)-N
-  100 Mbps: amber:speed-(lan|wan)-N
-   10 Mbps: (none, turned off)
