[PATCH] riscv/console: Updated the console-config.c file

[Somesh Deshmukh]

- Parsing the sub-node should be available generic not specific to Freedom
  Arty310 board. If we remove the Freedom Arty macro now, it will lose
  backward compatibility.The proposed change will retain the backward
  compatibility and also adds the necessary fix for parsing sub-node.

- Line 234 and 235 in riscv_console_probe() uses polled handlers for ns16550
  read and write while, the console_initialize function uses ns16550
  interrupt handler. Proposing a fix to make polled handlers consistant
  through out the console-config.c
