drm/amdgpu: Add mode2 reset support for aldebaran
v1: Aldebaran uses reset control to support mode2 reset. The sequences to reset and restore hardware context are specific to a particular configuration. v2: Clear bus mastering before reset. Fix coding style issues, drop unwanted variables and info log.
