Subject: [PATCH] x86/PCI/ACPI: Replace printk calls with pr_info/pr_warn calls

The direct use of printk is deprecated, replace the printk calls
in arch/x86/pci/acpi.c with pr_info/pr_warn calls.

Signed-off-by: Hans de Goede <hdegoede@...hat.com>

Note this applies on top of my:
"x86/PCI: Ignore E820 reservations for bridge windows on newer systems"
patch and was requested by several people during review of that patch.
