media: vim2m: remove unused CLIP macro

The CLIP macro, which was used to clamp color component values to the
[0, 255] range, is no longer used anywhere in the vim2m driver. Remove it
to clean up the code and avoid confusion.

The following issues were reported by checkpatch:
ERROR: Macros with complex values should be enclosed in parentheses
