The PCI support for Xen doesn't compile on ARM/ARM64 when
CONFIG_PCI_MMCONFIG=y:
drivers/xen/pci.c:31:25: fatal error: asm/pci_x86.h: No such file or
directory
#include <asm/pci_x86.h>
Although, Xen is not currently involved in PCI management for ARM/ARM64.
There is plan to support it, but it would require some changes in Linux
side.
For now, introduce a new config options XEN_PCI which will be turned off
for ARM platform.
