char: cadence: correct reset value for baud rate registers

The Cadence UART device emulator stores 'baud rate generator'
and 'baud rate divider' values, used in computing speed, in two
registers. The device specification defines their range and
their reset value. Use their correct value when resetting the
device in cadence_uart_reset.
