riastradh | pci_resource(9): Handle multiple ranges of the same type.
Rather than having the caller fill in an array indexed by range type
of a single start/end pair for each type, the caller will now do:
struct pci_resource_info info;
memset(&info, 0, sizeof(info));
pci_resource_add_range(&info, PCI_RANGE_MEM, mstart1, mend1);
pci_resource_add_range(&info, PCI_RANGE_MEM, mstart2, mend2);
pci_resource_add_range(&info, PCI_RANGE_MEM, mstart3, mend3);
pci_resource_add_range(&info, PCI_RANGE_PMEM, pstart1, pend1);
pci_resource_add_range(&info, PCI_RANGE_IO, iostart1, ioend1);
...
While here, fix a format string -- 0x% or %# is enough to say that
the output is hexadecimal; we don't need to belabour the point by
printing a `0x0x' prefix!
XXX While this handles multiple io/mem/prefetchable-mem ranges, it
doesn't yet handle multiple bus ranges, which we have seen in
practice, e.g. on orion o6. TBD.
