When ACPI is enabled on ARM64, XEN ACPI will also compiled
into the kernel, but XEN ACPI is x86 dependent, so introduce
CONFIG_XEN_ACPI to make it depend on x86 before XEN ACPI is
functional on ARM64.

I think XEN_DOM0 (in arch/x86/xen/Kconfig) should select this option. 
Otherwise, if it is set to 'n', we won't be able to build enlighten.c 
(xen_start_kernel() -> xen_acpi_sleep_register() refers to 
xen_acpi_notify_hypervisor_sleep()).

I don't think that it is necessary: XEN_ACPI gets automatically enabled
anyway.

In which case, can I have your Ack on this please?
