For layer_split:
Enable it if the scaling exceed the accept range of scaler.

For image_enhancer:
Enable it if the scaling is a 2x+ scaling

Imo should be two patches. Aside from that (and with 0 knowledge about the
hw, just looking at this from a kms/atomic uapi pov):

Hi Daniel:
I split this change to two patches, please ignore this one, and please
help to review the below sparated ones:
- https://patchwork.freedesktop.org/series/63340/ for layer_split
- https://patchwork.freedesktop.org/series/63341/ for image enhancer

Thanks
James
