Add the initial device  tree for  the R8A77980 SoC based Condor 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.

Changes in version 2:
- removed the useless "status" property from the SCIF_CLK node;
- fixed the memory size;
- added Geert's tag.
