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.

help
Enable support for the hardware based random number generator
module of the DCP. It uses the True Random Number Generator (TRNG)
and a Pseudo-Random Number Generator (PRNG) to achieve a true
randomness and cryptographic strength.
