[PATCH v3] soc: ti: knav_qmss_queue: free resources in remove callback

Implement the TODO in knav_queue_remove() by stopping PDSPs and
freeing queue regions and queue ranges before disabling runtime PM,
mirroring the cleanup performed in the probe error path.

This ensures resources are released on driver unbind and avoids
leaking queue/region state.
