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.
