+enable reset as a button
 fix battery pin usage
 drive TCXO DIO3 enable high whenever we want the clock
 use PIN_GPS_WAKE to sleep the GPS
 use tp_ser_io as a button, it goes high when pressed

 feedback to ttgo:
+use pcf8563 part for waking CPU? or remove it
+the mx25 flash chip is great!
 name: TTGO LoraCard (nice googablity, unique name, sounds slick, implies lora and small)
 i'm going to add some sort of pass/fail factory test
 remove the cp2014 part
