drm/amdgpu/discovery: fix fw based ip discovery
commit 514678da56da089b756b4d433efd964fa22b2079 upstream.
We only need the fw based discovery table for sysfs. No
need to parse it. Additionally parsing some of the board
specific tables may result in incorrect data on some boards.
just load the binary and don't parse it on those boards.
Closes: https://gitlab.freedesktop.org/drm/amd/-/issues/4441
Fixes: 80a0e8282933 ("drm/amdgpu/discovery: optionally use fw based ip discovery")
