With prediction resistance enabled, on every random number request
CAAM is forced to do reseeding of DRBG, which is time taking process
which leads to lower Random number generation performance.
So to give user the flexibility to enable/disable this feature a flag
CFG_CAAM_RNG_RUNTIME_PR is introduced.
By default it will be disabled and user can enable it as per its
requirement.
