[07/18] ARM: dts: r8a7742: Initial SoC device tree

Commit Message

Basic support for the RZ/G1H (R8A7742) SoC. Added placeholders
for the peripherals supported by the SoC which will be filled up
by incremental patches.

Please remove the placeholders, as there is nothing that depends on their
presence.

Please drop the audio and CAN clocks for now, as they are not used.

This should be used (see below).

I prefer to see a real node for the serial console, so the system can at
least be boot tested to a console prompt.
Note that this requires adding a minimal board DTS, too.

OK so in that case Ill enable scifa2 and SDHI interface so it can be bootable.
