serial: qcom-geni: fix opp vote on shutdown
commit 8ece7b754bc34ffd7fcc8269ccb9128e72ca76d8 upstream.
The operating-performance-point vote needs to be dropped when shutting
down the port to avoid wasting power by keeping resources like power
domains in an unnecessarily high performance state (e.g. when a UART
connected Bluetooth controller is not in use).
