Doesn't look that way:

  $ riscv64-softmmu/qemu-system-riscv64 -device help 2>&1 | head -5
  Controller/Bridge/Hub devices:
  name "pci-bridge", bus PCI, desc "Standard PCI Bridge"
  name "pci-bridge-seat", bus PCI, desc "Standard PCI Bridge (multiseat)"
  name "vfio-pci-igd-lpc-bridge", bus PCI, desc "VFIO dummy ISA/LPC bridge for 
IGD assignment"

  $

Looking at the output of '-device help' in its entirety, I think
there's a lot of stuff in there that doesn't quite belong with a
RISC-V guest and that it would probably make sense to compile out.
