ACPICA: Events: Introduce ACPI_REG_DISCONNECT invocation to acpi_ev_execute_reg_methods()

Browse Source 
ACPICA commit 1cf1a1e090f61f0c27f1dcf1905c7cc79a9c51c8

It is likely that we should synchronously invoke _REG(DISCONNECT) only when
the acpi_remove_address_space_handler() is invoked because of dependencies.
If it is invoked when the object is not referenced, problem may occur
if the operation region fields accessed in _REG are no longer driven by any
device driver.

Noticed that _REG(CONNECT)/_REG(DISCONNECT) only mean to inform the AML of
the handler availability, no return value is required for the caller.

This patch only introduces ACPI_REG_DISCONNECT invaocation, but doesn't
introduce a real change. Lv Zheng.
