Subject: ACPICA: Revert "iASL: change processing of external op namespace
 nodes for correctness"
Patch-mainline: v4.19-rc1
Git-commit: da7f7126f04c37cf0b33a75b7a5dd3c1b2adfa2b
References: bsc#1117419

Revert commit b43eac6f3384 (ACPICA: iASL: change processing of
external op namespace nodes for correctness; upstream ACPICA
commit aa866a9b4f24bbec9f158d10325b486d7d12d90f).

This was done in order to allow more relaxed usage of ASL external
declarations.
