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

Browse source 
commit 4dd8752a14 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).
