Commit Message

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
<[e-mail]>.

    Forgot to specify SCIF_CLK -- it's populated.
