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

commit 4abb951b73ff0a8a979113ef185651aa3c8da19b upstream.

The table load process omitted adding the operation region address
range to the global list. This omission is problematic because the OS
queries the global list to check for address range conflicts before
deciding which drivers to load. This commit may result in warning
messages that look like the following:

[    7.871761] ACPI Warning: system_IO range 0x00000428-0x0000042F conflicts with op_region 0x00000400-0x0000047F (\PMIO) (20180531/utaddress-213)
[    7.871769] ACPI: If an ACPI driver is available for this device, you should use it instead of the native driver

However, these messages do not signify regressions. It is a result of
properly adding address ranges within the global address list.
