PCI: make PCI bus resource messages more meaningful

Change PCI bus resource messages so they have a bit more context
and look like the rest of PCI, e.g.,

    - bus: 00 index 0 io port: [0x00-0xffff]
    - bus: 00 index 1 mmio: [0x000000-0xffffffff]
    + pci 0000:00: bus resource 0 io : [0x00-0xffff]
    + pci 0000:00: bus resource 1 mem: [0x000000-0xffffffff]

This also changes them from KERN_INFO to KERN_DEBUG.
