video: driver: inline preprocessing improvement

For VPSS, FW requests more bandwidth from HW.
In order to support inline processing, FW introduced
request preprcess property.

Enble this property only when following conditions are met:
- CAC-BRS is required
- don't have EVA stats.
- Upto 4k@60 fps, max( frame rate, operating rate) <= 60
