MLK-19689 drm/imx/dcss: Fix scaler freeze on channel-0 

For channel 0 if 1920x1080@NV12 was used when setting a mode would
freeze the scaler. That's because the chroma vertical size was set to
540 (1920 / 2) instead of 544 (which is divisible to 8).

This patch makes sure we round up the chroma vertical size for channel-0
properly.
