In video mode, it doesn't need to even call decon_setup_trigger function even though this function is just returned.

The function is inlined anyway so it does not matter from efficiency point of view. The good point in this change is that it puts trigger related code into one function making decon_commit little bit less messy.

I don't see how much this change mitigates making decon_commit to be messy because already same codes are here and there. Anyway really trivial thing. Will merge it.
