[PATCH v3 03/17] xen/arm: solve compilation error on ARM with ACPI && HAS_PCI

[Rahul Singh <rahul.singh@xxxxxxx>]

prelink.o: In function `pcie_aer_get_firmware_first’:
drivers/passthrough/pci.c:1251: undefined reference to `apei_hest_parse'

Compilation error is observed when ACPI and HAS_PCI is enabled for ARM
architecture. APEI not supported on ARM yet move the code under
CONFIG_X86 flag to gate the code for ARM.
