Revert "{northbridge,soc,southbridge}: Don't use both of _ADR and _HID"
This reverts commit 01787608670adec26fcea48173e18395e51c790e.
AMD: Dropping the _HID of PCI root bus doesn't work well and people
started to notice the breakage.
Intel: These platforms have a devicetree switch to choose between PCI
and ACPI modes. In the former case we need _ADR, but in the latter _HID
as the PCI devices are hidden.
The conflicting use of _ADR and _HID still needs to be fixed before
we can bump our IASL version.
