5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Rob Herring (Arm) <robh@xxxxxxxxxx>
commit 75f1f311d883dfaffb98be3c1da208d6ed5d4df9 upstream.
This reverts commit 267b21d0bef8e67dbe6c591c9991444e58237ec9.
Turns out some DTs do depend on this behavior. Specifically, a
downstream Pixel 6 DT. Revert the change at least until we can decide if
the DT spec can be changed instead.
