serial: qcom-geni: drop bogus runtime pm state update

commit 4dd8752a14ca0303fbdf0a6c68ff65f0a50bd2fa upstream.

The runtime PM state should not be changed by drivers that do not
implement runtime PM even if it happens to work around a bug in PM core.

With the wake irq arming now fixed, drop the bogus runtime PM state
update which left the device in active state (and could potentially
prevent a parent device from suspending).
