For i.MX6ULL the engine Software (SW) must used for the image
validation.

Changes in v3:
- move habv4-imx6-gencsf.h to habv4-imx6-gencsf-template.h and rework it
- create new habv4-imx6-gencsf.h
- rework habv4-imx6ull-gencsf.h
Changes in v2:
- Rework the file habv4-imx6-gencsf.h, because cst 3.3.1 fails for engine
software with parameter Feature.
