soundwire: debugfs: use controller id and link_id for debugfs

[ Upstream commit 75eac387a2539aa6c6bbee3affa23435f2096396 ]

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!"
