That is UART_DM_MR1

But this is UART_MR1. The two hardware cores share the same driver because the DM hardware is based on the non-DM hardware. I suppose we need to make another #define UART_DM_MR1_AUTO_RFR_LEVEL1 and then have an if (msm_port->is_uartdm) in msm_startup() path to handle the differences here.
