[PATCH 01/10] drm/amdgpu: add GFX RAS common function

[Alex Deucher]

From: Tao Zhou <tao.zhou1 at amd.com>

The common function can help reduce redundant code.

v2: remove xcp operation, only need to do RAS operations for all
instances.
v3: remove check for GFX RAS support, will be checked in higher level.
    add amdgpu prefix for the function name.
