Subject: [PATCH] slimbus: qcom-ngd-ctrl: Correct PDR and SSR cleanup ownership

PDR and SSR callbacks are registred from the controller probe function,
but currently released from the child device's remove function.

The remove() function should only be unwinding what was done in the
same device's probe() function.
