serial: pxa: Implement default_serial_console in serial_pxa.c

Browse Source 
Implement weak default_serial_console() function in serial_pxa
driver, which gets available in case CONFIG_SERIAL_MULTI is
enabled. This will get helpful in subsequent patches, which will
encapsulate PXA's struct serial_device instances in serial_pxa
driver.
