[PATCH 50/55] media: rkisp1: Add and set registers for crop for i.MX8MP

Tue Jun 14 12:11:22 PDT 2022
The ISP version in the i.MX8MP has a separate set of registers for crop
that is currently not handled. Add a feature flag to determine which
type of crop the ISP supports and set the crop registers based on that.
