Add the feature for the flexcomm uart to be able to be a wakeup source from low power modes. To be able to do this on a relevant platform, the DT node for the UART needs to have the wakeup-source property and define a "sleep" clock. The details of handling the sleep clock and default clock are still platform specific but handled by the clock control driver of the platform, so that this code should be able to be applicable to any platform that follows the same DT definition.
