Do not setup userial_ports array as const because
in uartlite_serial_putc is out_be32 which can't write
to tx_fifo if is const.

There are several approach how to solve it in uartlite_serial_putc.
1. add retype to out_be32 function
2. retype in assignment
3. do not define userial_ports as const - used solution
