parisc: Use serial port addresses for console I/O from PAGE0

The structs mem_kbd and mem_cons holds the HPA of the serial ports
used for console I/O, so use those instead of hardcoding to
PARISC_SERIAL_CONSOLE.

There is no functional change with this, but now it complies to how
the values from PAGE0 should be used.
