This commit adds the relevant details in the Armada 7K/8K Device Tree to properly mux the UART used for the serial console. Since there is basically only one possible muxing for the UART0 on the AP, the muxing configuration is described in armada-ap806.dtsi, and selected from the individual boards (other boards could be using a different UART).

Applied on mvebu/dt64-4.15 Thanks, Gregory
