Subject: [PATCH] drm/amdgpu: allow direct upload save restore list for raven2

From: changzhu <Changfeng.Zhu at amd.com>

It will cause modprobe atombios stuck problem in raven2 if it doesn't
allow direct upload save restore list from gfx driver.
So it needs to allow direct upload save restore list for raven2
temporarily.
