Fix:

  hw/acpi/pcihp.c:499:36: error: declaration shadows a variable in the global scope [-Werror,-Wshadow]
                       MemoryRegion *address_space_io,
                                     ^
  include/exec/address-spaces.h:35:21: note: previous declaration is here
  extern AddressSpace address_space_io;
                      ^
