If the FDT contains /chosen/rng-seed, then the Linux RNG will use it to
initialize early. Set this using the usual guest random number
generation function. This is confirmed to successfully initialize the
RNG on Linux 5.19-rc2.

This is mostly borrowed from xtensa and riscv as examples. The
create_pcie_irq_map swizzle function is almost and exact copy
but here we use a single cell interrupt, possibly we can make
this generic.

This patch adds the OpenRISC virtual machine 'virt' for OpenRISC. This
platform allows for a convenient CI platform for toolchain, software
ports and the OpenRISC linux kernel port.
Much of this has been sourced from the m68k and riscv virt platforms.
The platform provides:
- OpenRISC SMP with up to 4 cpus
- A virtio bus with up to 8 devices
- Standard ns16550a serial
- Goldfish RTC
- SiFive TEST device for poweroff and reboot
- Generated Device Tree to automatically configure the guest kernel
