Modify it to force join 'n' number of pipes, where n is a valid pipe joiner configuration. This will help in case of ultra joiner where 4 pipes are joined. v2: -Fix commit message to state that only valid joiner config can be forced. (Suraj) -Rename the identifiers to have INTEL_BIG/NONE_JOINER_PIPES. (Suraj) v3: -Avoid enum for joiner pipe counts, use bare numbers for better readability.
