2G/2G/4G routers have some special leds functions:
- signal strength, which shows info about signal status.
Some devices have multicolor indication (e.g. D-Link DWR-960)
other use multiple leds for different levels (e.g. Cell-C RTL30VW)
- connection status, which shows if connection is active. Some devices
have multiple leds for different bands (e.g. D-Link DWR-960).
- sms indicator
This patch adds new LED_FUNCTION_* defines of them.
