MLK-21445 serial: fsl_lpuart: do HW reset for communication port Do HW reset for communication port after the port is registered if the UART controller support the feature. Do partition reset with LPUART's power on, LPUART registers will keep the previous status, like on i.MX8QM platform, which is not expected action, so reset the HW is required. Currently, only i.MX7ULP and i.MX8QM LPUART controllers include global register that support HW reset.
