[PATCH] p54: fix SoftLED compile dependencies

[Christian Lamparter <chunkeey-S0/GAf8tV78@public.gmane.org>]

This patch fixes a compile problem when the MAC80211_LEDS
triggers are enabled but not LED class itself. 
(which is sort of pointless, but anyway...)

mb, thank you for the tips!

Randy Dunlap can you please give this patch a try?

John, do you know where the patch form 
Geert Uytterhoeven <geert-Td1EMuHUCqxL1ZNQvxDV9g@public.gmane.org> went?
