[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.
