From: Binoy Jayan

Semaphore are going away in the future, so remove the unused function
wilc_lock_timeout which calls a semaphore api but has no users.

They following is a patch [v2] which removes semaphores from wilc1000.
Its part of a bigger effort to eliminate all semaphores
from the linux kernel.

Arnd, Thank you for reviewing. Removed the prototype as well.
