Add corresponding compatible strings. Note: Several NXP SoC from QorIQ family (P1010, P1023, P4080, P3041, P5020) also have a RNGB, however it's part of the CAAM (Cryptograhic Accelerator and Assurance Module) crypto accelerator. In this case, RNGB is managed in the caam driver (drivers/crypto/caam/), since it's tightly related to the caam "job ring" interface, not to mention CAAM internally relying on RNGB as source of randomness. On the other hand, the i.MX6 SoCs with RNGB have a DCP (Data Co-Processor) crypto accelerator and this block and RNGB are independent.
