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

[Md Shofiqul Islam <shofiqtest@gmail.com>]

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

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