Subject: soundwire: debugfs: use controller id instead of link_id

From: Srinivas Kandagatla <[email protected]>

commit 6d5e7af1f6f5924de5dd1ebe97675c2363100878 upstream.

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

Fixes bf03473d5bcc ("soundwire: add debugfs support")
