The UART device used by the backend needs to be gotten before use, and put after. In limited cases, device drivers call pm_device_runtime_get() as part of the call to uart_rx_enable(), this is not the case for polling, nor interrupt driven API calls for most if not all drivers, nor is that expected. Implement pm_device_runtime calls in shell uart backend similar to the logging uart backend to support all uart drivers in all configurations.
