Update /dev/ttyAMA0 UART pinout

[Armin@netPI]

I have one question concerning netFIELD Connect gateway. Why don't you put the orginal SD card of this device aside and use a brand new one and load the original Raspbian OS onto it and insert this one into the netFIELD Connect gateway. Then you have the best development environment ever. And if you then follow this link here https://www.raspberrypi.org/blog/docker-...pberry-pi/ you post install then also Docker and everything is setup fine for a development.
