usb: typec: qcom-pmic-typec: disable cc_debounce_dwork on stopgrafted

cc_debounce_dwork is queued from the set_cc() and start_toggling()
callbacks, which run from TCPM's kthread worker.  port_stop() returns
before tcpm_unregister_port() destroys that worker.  Flushing the worker
during unregister may therefore run a callback which queues the delayed
work after port_stop() has returned.

The delayed work can then run after devres has freed pmic_typec_port.

Use disable_delayed_work_sync() in port_stop() to cancel a pending
instance and prevent the TCPM callbacks from queueing another one.

This issue was found by an in-house static analysis tool.
