ARM: dts: sun8i: Add pinmux set for uart0
uart0 on sun8i is only muxed with mmc0, which makes it a poor choice for the console. However, some tablets only have pads for uart0 available on the circuit board. Here we add the uart0 pinmux set for people who need it. Signed-off-by: Chen-Yu Tsai <wens@csie.org> Signed-off-by: Maxime Ripard <maxime.ripard@free-electrons.com>
