Peter Tyser 983eb9d162 pci: Clean up PCI info when CONFIG_PCI_SCAN_SHOW 
This change does the following:
- Removes the printing of the PCI interrupt line value.  This is
  normally set to 0 by U-Boot on bootup and is rarely used during
  everyday operation.

- Prints out the PCI function number of a device.  Previously a device
  with multiple functions would be printed identically 2 times, which is
  generally confusing.  For example, on an Intel 2 port gigabit Ethernet
  card the following was displayed:
    ...
    04  01  8086  1010  0200  00
    04  01  8086  1010  0200  00
    ...

- Prints a text description of each device's PCI class instead of the
  raw PCI class code.  The textual description makes it much easier to
  determine what devices are installed on a PCI bus.

- Changes the general formatting of the PCI device output.

Previous output:
