Revert "ACPICA: AML interpreter: add region addresses in global list during initialization"

This reverts commit 22083c028d0b3ee419232d25ce90367e5b25df8f which is
commit 4abb951b73ff0a8a979113ef185651aa3c8da19b upstream.

This commit was tagged with:

Link: https://bugzilla.kernel.org/show_bug.cgi?id=200011
Tested-by: Jean-Marc Lenoir
Cc: All applicable <stable@vger.kernel.org>
making it sound like it was fixing an actual bug. This is not the case.
The commit fixes a side issue discovered while investigating bug
#200011. It does NOT fix bug #200011 itself (as explicitly reported by
Jean-Marc at https://bugzilla.kernel.org/show_bug.cgi?id=200011#c65 ).

It does however cause regressions, despite what the commit message says. See:

https://bugzilla.kernel.org/show_bug.cgi?id=201721

and I expect more similar regressions, as ACPI resource conflicts are
very frequent.

This commit was not stable material to start with. It is intrusive,
presents a risk of side effects, and does not solve an actual bug that
is bothering users.
