acpi: add aml_int() term

Browse source 
* factor out ACPI const int packing out of build_append_value()
  and rename build_append_value() to build_append_int_noprefix()
  it will be reused for adding a plain integer value into AML.
  will be used by is aml_processor() and CRS macro helpers
* extend build_append_int{_noprefix}() to support 64-bit values
  it will be used PCI for generating 64bit _CRS entries
