This patch set already tested on multi platforms:
 - AMD Seattle board;
 - Cavium Thunder board;
 - Huawei D02 board;
 - Qualcomm ARM64 platform

This version 10 patch set address some minor comments and collect ACKs and
Reviewed-bys for v9:

 - new Acks from Rafael, Olof, Grant, Lorenzo
 - new way to handle typdef phys_cpuid_t which suggested by Rafael,
   but no functional change
 - Remove if(!phys) for early ioremappings
 - Rework sleep function for ARM64
 - Introduce linux/acpi_irq.h to hold acpi_irq_init()
 - Disable ACPI if not HW_REDUCED_ACPI compliant
 - Remove the doc of why ACPI on ARM

Thanks
Hanjun
