PCI: probing debug message uniformization

Browse Source 
This patch uniformizes PCI probing debug boot messages with dev_printk()
intead of manual printk()

It changes adress range output from [%llx, %llx] to [%#llx-%#llx], like
in pci_request_region().

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: [0xf4280000-0xf4283fff]
pci 0000:00:1b.0: PME# supported from D0 D3hot D3cold

This patch has been runtime tested, boot log messages diffed, everything
looks OK.
