drm/amdgpu: Increase soft IH ring size

2023-07-12T14:57:25Z

Retry faults are delegated to soft IH ring and then processed by deferred worker. Current soft IH ring size PAGE_SIZE can store 128 entries, which may overflow and drop retry faults, causes HW stucks because the retry fault is not recovered. Increase soft IH ring size to 8KB, enough to store 256 CAM entries because we clear the CAM entry after handling the retry fault from soft ring. Define macro IH_RING_SIZE and IH_SW_RING_SIZE to remove duplicate constant. Show warning message if soft IH ring overflows with CAM enabled because this should not happen.
