arm64: dts: renesas: initial Eagle board device tree
Add the initial device tree for the R8A77970 SoC based Eagle board.
The board has 1 debug serial port (SCIF0); include support for it,
so that the serial console can work.
Based on the original (and large) patch by Vladimir Barinov
<vladimir.barinov@cogentembedded.com>.
