[PATCH v2 2/2] arch: arm: mach-imx: Add habv4 config file for i.MX6ULL

[Maik Otto]

The i.MX6ULL has no CAAM engine for Secure Boot on HABv4 (NXP AN4581).
For i.MX6ULL the engine Software (SW) must used for the image
validation.

Changes in v2:
    - Rework the file habv4-imx6-gencsf.h, because cst 3.3.1 fails for engine
      software with parameter Feature.
