Apply flush workaround on S5 Mini devices with Exynos chipset.

Also apply the workaround for the secure variant of OMX.SEC.avc.dec.
Note that it's not necessary to do the same for the RK decoder in
the method below, since that workaround is targeted at SDK_INT<=17
and secure decoders only came along in 18.
