imx: Refactoring CAAM Job Ring structure and Secure Memory for imx7
Refactored data structure for CAAM's job ring and Secure Memory
to support i.MX7.
The new memory map use macros to resolve SM's offset by version.
This will solve the versioning issue caused by the new version of
secure memory of i.MX7
