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.
