Hi Bin：
There are a little difference about acpi specification between the arm and x86，so the arm-acpi-support is needed.
Thank you Steven Hao

This adds acpi code for arm and the acpi tables about Phytium Durian Board. The acpi table only support rsdp, rsdt, xsdt, fadt, dsdt, ssdt, gtdt, madt, mcfg, iort, spcr.

One generic comment, could you please check whether the existing x86 ACPI support can be reused/refactored to support ARM?
