[media] media: s5p-mfc: use vb2_ops_wait_prepare/finish helper
This patch drops driver specific wait_prepare() and wait_finish() callbacks from vb2_ops and instead uses the the helpers vb2_ops_wait_prepare/finish() provided by the vb2 core, the lock member of the queue needs to be initalized to a mutex so that vb2 helpers vb2_ops_wait_prepare/finish() can make use of it.
