soundwire: bus: demote UNATTACHED state warnings to dev_dbg()

Browse Source 
[ Upstream commit 2c96956fe7 ]

The dev_warn() messages in sdw_handle_slave_status() for UNATTACHED
transitions were added in commit d1b3285570 ("soundwire: bus: add
dev_warn() messages to track UNATTACHED devices") to debug attachment
failures with dynamic debug enabled.

These warnings fire during normal operation -- for example when a codec
driver triggers a hardware reset after firmware download, causing the
device to momentarily go UNATTACHED before re-attaching -- producing
misleading noise on every boot.

Demote the messages to dev_dbg() so they remain available via dynamic
debug for diagnosing real attachment failures without alarming users
during expected initialization sequences.

Fixes: d1b3285570 ("soundwire: bus: add dev_warn() messages to track UNATTACHED devices")
