This is just a handy routine that reports last PCI busno: we walk
down all the hoses and return last hose's last_busno.
Will be used by PCI/PCIe initialization code.

It is no longer always true that the pci bus address can be
used as the virtual address for pci accesses. pci_map_bar()
is created to return the virtual address for a pci region.

When we search for an address match in pci_hose_{phys_to_bus,bus_to_phys}
we should give preference to memory regions that aren't system memory.
Its possible that we have over mapped system memory in the regions and
we want to avoid depending on the order of the regions.

PCI bus is inherently 64-bit. While not all system require access to
the full 64-bit PCI address range some do. This allows those systems
to enable the full PCI address width via CONFIG_SYS_PCI_64BIT.

This patch moves the check, if a device should be skipped in PCI PNP
configuration into the function pci_skip_dev(). This function is defined
as weak so that it can be overwritten by a platform specific one if
needed. The check if the device should get printed in the PCI summary upon
bootup (when CONFIG_PCI_SCAN_SHOW is defined) is moved to the function
pci_print_dev() which is also defined as weak too.

This commit gets rid of a huge amount of silly white-space issues.
Especially, all sequences of SPACEs followed by TAB characters get
removed (unless they appear in print statements).
Also remove all embedded "vim:" and "vi:" statements which hide
indentation problems.

Physical addrs need to be represented by phys_addr_t, not
unsigned long. Otherwise, systems that use CONFIG_PHYS_64BIT
are going to fail mightily.

In current source code, when the device number of PCI is 0, process PCI
bridge without fail. However, when the device number is 0, it is not PCI
always bridge. There are times when device of PCI allocates.
When CONFIG_PCI_SKIP_HOST_BRIDGE is enable, this problem is solved when
use this patch.
