Fix baudrate value 5150000 which was added in commitead4864fa6("arm: mvebu: a38x: Define supported UART baudrates"). Exact value for divisor 3 with 250 MHz TCLK is 5208333 baudrate. In above commit I incorrectly rounded it to 5150000 value due to testing with USB-UART hw which incorrectly reported exact value and divisor configured on other other end of UART link. Fix this value to 520000 baudrate which is more close to the exact hardware value and also has less fraction parts.
