Erik Schmauss c5781ffbbd ACPICA: Namespace: remove address node from global list after method termination 
ACPICA commit b233720031a480abd438f2e9c643080929d144c3

ASL operation_regions declare a range of addresses that it uses. In a
perfect world, the range of addresses should be used exclusively by
the AML interpreter. The OS can use this information to decide which
drivers to load so that the AML interpreter and device drivers use
different regions of memory.

During table load, the address information is added to a global
address range list. Each node in this list contains an address range
as well as a namespace node of the operation_region. This list is
deleted at ACPI shutdown.

Unfortunately, ASL operation_regions can be declared inside of control
methods. Although this is not recommended, modern firmware contains
such code. New module level code changes unintentionally removed the
functionality of adding and removing nodes to the global address
range list.

A few months ago, support for adding addresses has been re-
implemented. However, the removal of the address range list was
missed and resulted in some systems to crash due to the address list
containing bogus namespace nodes from operation_regions declared in
control methods. In order to fix the crash, this change removes
dynamic operation_regions after control method termination.
