[PATCH 3/3] serial: qcom-geni: drop bogus runtime pm state update

[Johan Hovold <johan+linaro@kernel.org>]

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).
