Please try the new patches in
https://github.com/hizukiayaka/gst-plugins-good
And look at this commit
https://github.com/hizukiayaka/gst-plugins-good/commit/92b99ba9322cf8a1039b877315b12bc9813e95cf

NOTE: even you could set those extra controls and driver accepted. It
doesn't mean it would work.
I looked at the s5p-mfc driver, it just set it then leave it alone. I
may fix this bug in the few weeks.
