a5fe1a03f7 ACPICA: fix leak of acpi_os_validate_address
http://bugzilla.kernel.org/show_bug.cgi?id=13620

If the dynamic region is created and added to resource list over and over again,
it has the potential to be a memory leak by growing the list every time.

This patch fixes the memory leak, as below

1) add a new field "count" to struct acpi_res_list.

   When inserting, if the region(addr, len) is already in the resource
   list, we just increase "count", otherwise, the region is inserted
   with count=1.

   When deleting, the "count" is decreased, if it's decreased to 0,
   the region is deleted from the resource list.

   With "count", the region with same address and length can only be
   inserted to the resource list once, so prevent potential memory leak.

2) add a new function acpi_os_invalidate_address, which is called when
   region is deleted.

3371c19c29 ACPICA: Remove ACPI_GET_OBJECT_TYPE macro
Remove all instances of this obsolete macro, since it is now a
simple reference to ->common.type. There were about 150 invocations
of the macro across 41 files. ACPICA BZ 755.
