+-M virt,dumpdtb is missing information from the device tree
+Description of problem:
+dumpdtb no longer produces a device tree with the full system described.

+Steps to reproduce:
+1. qemu-system-riscv64 -machine virt,dumpdtb=test.dtb
+2. dtc -I dtb -O dts test.dtb
+Additional information:
+The regression was introduced in https://gitlab.com/qemu-project/qemu/-/commit/8fd2518ef2f8d. If this commit is reverted, the expected behavior returns.
