riscv, qemu_fw_cfg: Add support for RISC-V architecture
Qemu fw_cfg support was missing for RISC-V, which made it hard to do
proper vmcore dumps from qemu.
Add the missing RISC-V arch-defines.
You can now do vmcore dumps from qemu. Add "-device vmcoreinfo" to the
qemu command-line. From the qemu monitor:
(qemu) dump-guest-memory vmcore
The vmcore can now be used, e.g., with the "crash" utility.
