qrap: Introduce machine-specific PCI address base
For pc machines, devices are placed directly on pci.0 with addresses like bus=pci.0,addr=0xa and in this case the existing code works correctly. For q35 machines, however, a separate PCI bus is created for each devices using a pcie-root-port, and the resulting addresses look like bus=pci.9,addr=0x0 In this case, we need to treat PCI addresses as decimal, not hexadecimal, both when parsing and generating them. This issue has gone unnoticed for a long time because it only shows up when enough PCI devices are present: for small numbers, decimal and hexadecimal overlap, masking the issue.
