soc: ti: knav_qmss_queue: Implement resource cleanup in remove()

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.

Set device_ready to false before cleanup to prevent any further
use of the device during teardown.

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