I don't think it makes much sense to split this in two parts...
Furthermore, shouldn't this be handled by the serial core, calling
uart_change_pm()?
It looks like uart_resume_port() already changes the port's state to
enabled, while uart_suspend_port() assumes the port is already enabled,
and disables it.
Perhaps handling is not correct for some code paths?
