From: Mario Limonciello <[email protected]>commit 017fbb6690c22 ("drm/amdgpu/discovery: check ip_discovery fw file available") added support for reading an amdgpu IP discovery bin file for some specific products. If it's not found then it will fallback to hardcoded values. However if it's not found there is also a lot of noise about missing files and errors. Adjust the error handling to decrease most messages to DEBUG and to show at most one message to a user about the missing file at INFO level. Closes: https://gitlab.freedesktop.org/drm/amd/-/issues/4312
