Subject: [PATCH v2 1/2] dt-bindings: leds: add LED_FUNCTION_MOBILE for mobile network

Add LED_FUNCTION_MOBILE for LEDs that indicate status of mobile network
connection. This is useful to distinguish those LEDs from LEDs that
indicates status of wired "wan" connection.

example (on stock fw):

IIJ SA-W2 has "Mobile" LEDs that indicate status (no signal, too low,
low, good) of mobile network connection via dongle connected to USB
port.

- no signal: (none, turned off)
-   too low: green:mobile & red:mobile (amber, blink)
-       low: green:mobile & red:mobile (amber, turned on)
-      good: green:mobile (turned on)

Suggested-by: Hauke Mehrtens <hauke@...ke-m.de>
