Add the initial device tree for the R8A7743 SoC based SK-RZG1M board.
The board has one debug serial port (SCIF0); include support for it, so
that the serial console can work.
Based on the original (and large) patch by Dmitry Shifrin
<dmitry.shifrin@xxxxxxxxxxxxxxxxxx>.
Signed-off-by: Sergei Shtylyov <sergei.shtylyov@xxxxxxxxxxxxxxxxxx>
