dts: sun8i-h3: associate exposed UARTs on Orange Pi Boards
These H3 boards all expose UART1-3 on their expansion header. Since other functions can be muxed to these pins, they are explicitly disabled. To enable them, one could use DT overlays or U-boot commands: => fdt set /soc/serial@01c28c00 status okay Signed-off-by: Jorik Jonker <jorik@kippendief.biz> Signed-off-by: Maxime Ripard <maxime.ripard@free-electrons.com>
