Srinivas Kandagatla 4438a74570 soundwire: debugfs: use controller id and link_id for debugfs
[ Upstream commit 75eac387a2 ]

link_id can be zero and if we have multiple controller instances
in a system like Qualcomm debugfs will end-up with duplicate namespace
resulting in incorrect debugfs entries.

Using bus-id and link-id combination should give a unique debugfs directory
entry and should fix below warning too.
"debugfs: Directory 'master-0' with parent 'soundwire' already present!"
