[media] s5p-fimc: Fix fimc-lite system wide suspend procedure

Only suspend the video pipeline devices if they were active before
the pm.suspend() helper is called. This patch prevents following error:

/# echo mem > /sys/power/state
[   34.965000] PM: Syncing filesystems ... done.

[   35.105000] PM: Device exynos-fimc-lite.1 failed to suspend: error -22
[   35.105000] PM: Some devices failed to suspend
