[PATCH] x86/PCI: Add missing log facility and move to use pr_ macros in pcbios.c

[Krzysztof Wilczynski]

Make the log facility used to print warnings to be KERN_WARNING
explicitly, rather than rely on the current (or default) value
of the MESSAGE_LOGLEVEL_DEFAULT set in Kconfig.  This will make
all the warnings in the arch/x86/pci/pcbios.c to be printed
consistently at the same log facility.

Replace printk(KERN_<level> ...) with corresponding pr_ macros,
while adding the missing log facility.
