Michael Walle ea95f2142e crypto/fsl: add RNG support
Register the random number generator with the rng subsystem in u-boot.
This way it can be used by EFI as well as for the 'rng' command.

Enable support for the hardware based random number generator
module of the CAAM. The random data is fetched from the DRGB
using the prediction resistance flag which means the DRGB is
reseeded from the TRNG every time random data is generated.
