The snps,dw-apb-uart binding need to specify two clocks: "baudclk", "apb_pclk". But only "apb_pclk" is specified now. Because the driver preferentially matches the first clock. Otherwise, it matches the second clock instead of both clocks. So both of them use the same clock don't change the function.
