Subject: [PATCH v5 3/5] dts: sun8i-h3: associate exposed UARTs on Orange Pi Boards

From: Jorik Jonker <jorik@...pendief.biz>

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@...28c00 status okay
