Add missing log facility where two instances of printk() that did not
use any (so it would be using MESSAGE_LOGLEVEL_DEFAULT set in Kconfig)
to make all the warnings in the arch/x86/pci/pcbios.c to be printed
consistently at the same log facility. Also resolve the following
checkpatch.pl script warning:
WARNING: printk() should include KERN_<LEVEL> facility level
While adding the missing log facility move over to using pr_ macros
over using printk(KERN_<level> ...) and DBG().
Signed-off-by: Krzysztof Wilczynski <kw@xxxxxxxxx>

Changes in v2:
Change wording and include checkpatch.pl script warning.
Leverage pr_fmt and remove "PCI: " prefix used throught.
Move to pr_debug() over using DBG() from arch/x86/include/asm/pci_x86.h.
