The early "dump PCI config space" code skips many multi-function
devices. This patch fixes that, so it dumps all devices in PCI
domain 0.
We should not skip the rest of the functions if CLASS_REVISION is
0xffffffff. Often multi-function devices have gaps in the function ID
space, e.g., 1c.0 and 1c.2 exist but 1c.1 doesn't. The CLASS_REVISION
of the non-existent 1c.1 function will appear to be 0xffffffff.
We should only look at the HEADER_TYPE of function zero. Often the
"multi-function" is set in function zero, but not in other functions.

Impact: cleanup
Now that arch/x86/pci/pci.h is used in a number of other places as well,
move the lowlevel x86 pci definitions into the architecture include files.
(not to be confused with the existing arch/x86/include/asm/pci.h file,
which provides public details about x86 PCI)
Tested on: X86_32_UP, X86_32_SMP and X86_64_SMP

There are a couple of places where (P)Dprintk is used which is an old
compile time enabled printk wrapper. Convert it to the generic
pr_debug().
