MLKU-38-3 crypto: caam - add SNVS / SECVIO support

This is a squash of the following i.MX BSP commits
(rel_imx_4.19.35_1.1.0_rc2)

1. 8f6a17b41917 ("ENGR00289885 [iMX6Q] Add Secure Memory and SECVIO support.")
2. 8433c811e97a ("MLK-9710-18 snvs - make SECVIO module device tree correct")
3. 35bbc34e996b ("MLK-9769-23 Replace SECVIO of_irq_to_resource() with irq_of_parse_and_map()")
4. 3ac6edcd92d4 ("MLK-11360-01 crypto: caam_snvs: add snvs clock management")
5. 9d9ca7a03e3b ("MLK-11922 i.mx6: Linux 3.14.28 CAAM & SNVS enabled by default. JTAG, DS-5 attachment causes exceptions")
6. fcdaabf1bba2 ("MLK-17412-01: Fix secvio driver to have same driver name as DTS")

that have been reworked:

1.
-make SM depend on JR
-enable SM, SECVIO only on i.MX SoCs
-fix resource leak - add off_node_put() where needed

Split commit in three:
- SNVS/SECVIO driver
- Secure Memory driver
- DT changes

3.
JR changes dropped - no longer needed, already upstream in
commit 549077d7d8 ("crypto: caam - check irq_of_parse_and_map for errors")

4.
Split the patch in two:
-DT bindings changes
-driver changes

5.
Fixed conflicts in imx7d.dtsi - added caam_sm and irq_sec_vio nodes.

Split commit in 3:
-SECVIO/SNVS driver changes
-SECVIO/SNVS DT changes
-Secure Memory DT changes
