Revert "drivers/crypto/fsl: assign job-rings to non-TrustZone"

Commit 22191ac35344 ("drivers/crypto/fsl: assign job-rings to
 non-TrustZone") breaks HABv4 encrypted boot support in the
following i.MX devices:

- i.MX6UL
- i.MX7S
- i.MX7D
- i.MX7ULP

For preparing a HABv4 encrypted boot image it's necessary to
encapsulate the generated DEK in a blob. In devices listed
above the blob generation function takes into consideration
the Job Ring TrustZone ownership configuration (JROWN_NS)
and can be only decapsulated by the same configuration.

The ROM code expects DEK blobs encapsulated by the Secure World
environments which commonly have JROWN_NS = 0.

As U-Boot is running in Secure World we must have JROWN_NS = 0
so the blobs generated by dek_blob tool can be decapsulated
by the ROM code.

Job-rings assignment is now handled in OP-TEE OS, this commit can
be safely reverted.
