drm/amdgpu: Introduce cached_rptr and is_guilty callback in amdgpu_ring
This patch introduces the following changes:
- Add `cached_rptr` to the `amdgpu_ring` structure to store the read pointer before a reset.
- Add `is_guilty` callback to the `amdgpu_ring_funcs` structure to check if a ring is guilty of causing a timeout.
