hw/arm: xlnx-versal-virt: Add AMD/Xilinx TRNG device

Browse source 
Connect the support for Versal True Random Number Generator
(TRNG) device.

Warning: unlike the TRNG component in a real device from the
Versal device familiy, the connected TRNG model is not of
cryptographic grade and is not intended for use cases when
cryptograpically strong TRNG is needed.
