drm/amd/display: Clear pipe pointers on pipe reset
[Why] We want to clean up unnecessary asserts, one of which is an assert in resource_is_pipe_type that fires if a pipe has no stream and still has pointers to other pipes ("dangling state"). This gets hit because pipes are not properly cleaned up in reset_back_end_for_pipe. When resetting a pipe, the existing MPCC / ODM combine pointers are no longer valid, especially when we put ODM in bypass.
[How] - reset pipe pointers in reset_back_end_for_pipe - remove useless code to avoid confusion (a long time ago it had a reason to be there, not anymore)
