Subject: [RFC PATCH 7/8] Revert "ACPI / PNP: skip ACPI device nodes associated with physical nodes already"

This reverts commit 2905875344f977acd188a2b0f1d163491e91459b.

commit 2905875344f977acd188a2b0f1d163491e91459b was introduced to prevent
PNP device objects from being created for ACPI device nodes already associated
with platform devices.

This is not needed any more because the platform device node won't be created
if a device has already been attached to the PNPACPI scan handler.

Plus, in some cases, we may need both PNP node and platform node for the
same ACPI device object, on purpose, like what I will do in next patch.

Thus reverting this commit.
