drm/amdgpu: Add helper to initialize badpage info

Browse source

Add a separate function to read badpage data during initialization.
Reading bad pages will need hardware access and cannot be done during
reset. Hence in cases where device needs a full reset during
init itself, attempting to read will cause a deadlock.
