ti/am335x: Fix baudrate calculation

UART input clock is platform dependent. Also account for possible
    use of get_option() where baudrate is not compile-time constant.

The hardware reference on BeagleBone is from a 48 MHz oscillator input.
    With pre-divisor of 16 we get same register values as in table 19-25.
