[PATCH 4.19 23/93] Revert "drm/radeon: Fix EEH during kexec"

[Greg Kroah-Hartman]

From: Alex Deucher <alexander.deucher@xxxxxxx>

[ Upstream commit 8d13c187c42e110625d60094668a8f778c092879 ]

This reverts commit 6f7fe9a93e6c09bf988c5059403f5f88e17e21e6.

This breaks some boards.  Maybe just enable this on PPC for
now?
