The SEC Job Rings are now available as individual devices.
This would enable sharing of job rings between kernel and
user space. Job Rings can now be dynamically bound/unbound
from kernel.

Changes are made in the following layers of CAAM Driver
1. Controller driver
        - Does basic initialization of CAAM Block.
        - Creates platform devices for Job Rings.
(Earlier the initialization of Job ring  was done
 by the controller driver)

2. JobRing Platform driver
        - Manages the platform Job Ring devices created
          by the controller driver
