MLK-17459-4: drm: imx: dcss: fix weston

This patch fixes an issue introduced by the cropping patches which made
weston look bad. That's because use_dtrc flag was enabled if modifiers
were present. However, graphics plane can have modifiers too. This patch
adds an extra check.

Also, remove an unnecessary debug message.
