Subject[PATCH] PCI probing debug message uniformization
Hello,

Here is a patch to uniformize PCI probing debug messages at
boot with dev_printk() intead of manual printk()

for example, it goes from the mixed-style:

PCI: 0000:00:1b.0 reg 10 64bit mmio: [f4280000, f4283fff]
pci 0000:00:1b.0: PME# supported from D0 D3hot D3cold
to uniform:

pci 0000:00:1b.0: reg 10 64bit mmio: [f4280000, f4283fff]
pci 0000:00:1b.0: PME# supported from D0 D3hot D3cold
If people prefer the UPPERCASE "PCI:" prefix from dev_printk(),
that would be matter for another patch...

I'm currently running the kernel with that patch applied, and
diffed bootlog, everything looks OK
