MLK-23774 crypto: caam - fix SNVS / SECVIO building as module

Browse Source 
Configuring both caam/jr and snvs/secvio drivers as modules:
CONFIG_CRYPTO_DEV_FSL_CAAM_JR=m
CONFIG_CRYPTO_DEV_FSL_CAAM_SECVIO=m

fails with:

drivers/crypto/caam/secvio.o: In function `snvs_secvio_driver_init':
drivers/crypto/caam/secvio.c:339: multiple definition of `init_module'
drivers/crypto/caam/jr.o:drivers/crypto/caam/jr.c:854: first defined here
drivers/crypto/caam/secvio.o: In function `snvs_secvio_install_handler':
drivers/crypto/caam/secvio.c:137: multiple definition of `cleanup_module'
drivers/crypto/caam/jr.o:drivers/crypto/caam/jr.c:71: first defined here
scripts/Makefile.build:439: recipe for target 'drivers/crypto/caam/caam_jr.o' failed
make[3]: *** [drivers/crypto/caam/caam_jr.o] Error 1

This is due to trying to link two platform drivers in the same
"composite" object.

Since in fact snvs/secvio driver does not depend on caam/jr
(and should not depend on the other caam drivers in general [*]),
and to keep the fix small [**], avoid linking snvs/secvio with caam/jr.

[*] Currently the only dependency is related to I/O accessors (regs.h)
and endianness detection (ctrl.c).
>From this perspective, it's important for caam controller driver
(ctrl.c) to probe before snvs/secvio driver.

[**] The proper solution would be splitting snvs/secvio from caam
(drivers, DT bindings etc.), since snvs is just a "companion module"
of caam.
