fix(xilinx): remove console error message

If console is not found there is no way where to print information about
it. Currently only cdns/dcc/pl011 uarts are supported that's why remove
the message which none can see anyway.
But keep "else" part with comment to avoid misra c rule 15.7 violation
which is also missing in Versal NET implementation.
