crypto: caam - Add Platform driver for Job Ring
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
