[media] s5p-fimc: Do not allow changing format after REQBUFS
Protecting the color format with vb2_is_streaming() is not sufficient as this prevents changing the format only after VIDIOC_STREAMON. To prevent the color format reconfiguration as soon as buffers are allocated use vb2_is_busy() instead. Also make the videobuf queue ops structure static.
