drm/amd/display: filter out invalid bits in pipe_fuses
commit 682439fffad9fa9a38d37dd1b1318e9374232213 upstream.
[Why]
Reading pipe_fuses from register may have invalid bits set, which may
affect the num_pipes erroneously.
[How]
Add read_pipes_fuses() call and filter bits based on expected number
of pipes.
