Let U-Boot do initial initialization of CAAM and enable secure boot
support.

SEC0: RNG instantiated
...
This fixes these errors in Linux kernel:
[ 0.835787] caam 30900000.caam: Entropy delay = 3200
[ 0.865826] caam 30900000.caam: failed to acquire DECO 0
[ 0.871154] caam 30900000.caam: failed to instantiate RNG
With 22191ac35344 ("drivers/crypto/fsl: assign job-rings to non-TrustZone")
it lets CAAM driver in Linux kernel do proper initialization:
[ 0.826552] caam 30900000.caam: device ID = 0x0a16030000000000 (Era 8)
[ 0.826566] caam 30900000.caam: job rings = 3, qi = 0
[ 0.845186] caam algorithms registered in /proc/crypto
[ 0.848088] caam 30900000.caam: caam pkc algorithms registered in /proc/crypto
[ 0.850225] caam_jr 30901000.jr0: registering rng-caam
