On IIJ SA-W2, some multiple LEDs have no "function" property and only
"color" property is available for the newer binding of LED on Linux
Kernel.
9d93b6d091 ("mvebu: drop redundant label with new LED color/function
format") removes "label" property from LEDs, then, multiple "<color>:"
(ex.: "green:"/"red:") will be appeared and renamed to "<color>:_<num>"
(ex.: "green:_1", "green:_2", ...) by kernel.

Fix this issue by adding missing "function" (and "function-enumerator")
property to those LEDs on IIJ SA-W2.
