I prepared a patch for further reference:

Subject: [PATCH] XEN / ACPI: Make XEN ACPI depend on X86
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.
