drm/amdgpu: allow direct upload save restore list for raven2

BugLink: https://bugs.launchpad.net/bugs/1862429
commit eebc7f4d7ffa09f2a620bd1e2c67ddd579118af9 upstream.

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.
