hw/riscv: virt: Map high mmio for PCIe
Some peripherals require 64-bit PCI address, so let's map the high
mmio space for PCIe.
For RV32, the address is hardcoded to below 4 GiB from the highest
accessible physical address. For RV64, the base address depends on
top of RAM and is aligned to its size which is using 16 GiB for now.
