simplify creation of Serial1 #47

I'm totally cool with this :) You want to PR the change, or do you want me to add it together with shiftIn/Out stuff? Also if flash is DIO, UART1 should be available. |

since Serial is hardcoded for debug, its nice to use one of the extra uarts for talkin' to a GPS

makes it easier, just add HardwareSerial Serial1(2); and in setup: Serial1.begin(115200);
note that uart #1 is not available because it is shared with SPI flash, so it was not tested. uart #2 works great on gpio #16 + #17. no other gpio's are available
