colibri-imx7: enable SECURE_BOOT and CAAM

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

Output:
U-Boot 2019.07-00006-gb90d461f82-dirty (Aug 17 2020 - 15:41:42 +0300)

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
