ramips: use consistent naming scheme for LEDs

The upstream LED naming convention is "device:color:led-name", but it seems that many of supported boards in OpenWrt don't follow this approach.
The following patch fixes this inconsistency in dts{,i} files and updates base-files scripts for ramips target:
 * fixes wrong indentation
 * keeps case statements structure in same convention as in other scripts (no empty line after ";;", no indentation for case...esac body)
 * fixes wrong LED names for some of boards (makes them the same as in dts{,i} files)
 * combines boards with same configuration (ex. set_wifi_led "rt2800pci-phy0::radio" in 01_leds)
