Add DT node for the same. The device is marked TI_SCI_PD_SHARED as parts of this IP are also shared with the security co-processor and OP-TEE. The RNG node is added but marked disabled as it is firewalled off for exclusive use by OP-TEE. Any access to this device from Linux will result in firewall errors. We add the node for completeness of the hardware description.
