Revert "ACPICA: AML interpreter: add region addresses in global list during initialization"
This reverts commit 7876d54ad642fbbd1857d37528aa1ec8c5a2c592 which is
commit 4abb951b73ff0a8a979113ef185651aa3c8da19b upstream.

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.
