hw/arm: xlnx-versal-virt: Add Xilinx BBRAM device
Connect the support for Versal Battery-Backed RAM (BBRAM)
The command argument:
-drive if=pflash,index=0,...
Can be used to optionally connect the bbram to a backend
storage, such that field-programmed values in one
invocation can be made available to next invocation.
The backend storage must be a seekable binary file, and
its size must be 36 bytes or larger. A file with all
binary 0's is a 'blank'.
