mb/lowrisc/nexys4ddr: Actually fix the UART clock setup
Ron's code calculated the DLL and DLM registers of the 8250 UART, but
that's the job of the UART driver. uart_input_clock_divider isn't needed
anymore because the default value of 16 works.
As a bonus, the baud rate can now be selected in Kconfig, instead of
being hardcoded at 115200.
TEST=Booted the board at 9600 and 115200 baud.
