[PATCH] x86/PCI: Fix compile errors when CONFIG_PCI is disabled

[Hans de Goede <hdegoede@redhat.com>]

arch/x86/include/asm/pci_x86.h uses a number of data -types and defines
without including the headers which define these.

Instead so far it has been relying on files including it including the
necessary headers first.

Recently a include <asm/pci_x86.h> was added to arch/x86/kernel/resource.c
which does not include the necessary headers first.

Add the missing includes to arch/x86/include/asm/pci_x86.h to fix the
compile errors (with certain .config-s) when it is included from
arch/x86/kernel/resource.c.

Fixes: f10507a66e36 ("x86/PCI: Ignore E820 reservations for bridge windows on newer systems")
