Access to CAAM in non-secure mode must be enabled by the boot
loader first. The U-Boot CAAM driver enables access to CAAM in
non-secure mode by default. Hence enable the CAAM driver to
allow Linux accessing CAAM directly. This prevents error
messages like the following on Linux boot:
  caam 30900000.caam: Entropy delay = 3200
  caam 30900000.caam: failed to acquire DECO 0
  caam 30900000.caam: failed to instantiate RNG

While I noticed that I did not (yet) look closer into it. Good catch.
