serial: 8250: Add missing rxtrig_bytes on Altera 16550 UART
The Altera 16550 UART core supports FCR Rx Trigger Level setting, but the port definition in the driver is missing the rxtrig_bytes array specifying the trigger levels. Add the array to make the Rx Trigger Level setting available on this type of 16550 UART.
