drm/i915: Make semaphore modparam RO
A couple patches in the upcoming rework of semaphores will break if semaphores are toggled by the user at various times. Since the code cleanups there seem to be an overall win, and toggling semaphores at runtime is not a terribly useful thing to do, simply make the module parameter read-only.
