[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.
[ 35.035000] Freezing user space processes ... (elapsed 0.01 seconds) done.

[ 35.105000] dpm_run_callback(): platform_pm_suspend+0x0/0x5c returns -22
[ 35.105000] PM: Device exynos-fimc-lite.1 failed to suspend: error -22
[ 35.105000] PM: Some devices failed to suspend
