Until RPI 3 and Zero W the pl011 (uart0) was always on pin 14/15. So in order to take care of them and other boards in the future, we need to define UART pinmuxing on board level. This work based on Eric Anholt's patch "ARM: bcm2385: Don't force pl011 onto pins 14/15." and Fabian Vogt's patch "ARM64: dts: bcm2837: assign uart0 to BT and uart1 to pin headers".
