cover arm64: dts: renesas: Add Support for R-Car D3 and Draak

Hi Simon, Magnus,

This patch series adds minimal support for the R-Car D3 SoC and the Draak development board, allowing to boot from a ramdisk using a serial console.

- The first two patches add DT sources for R-Car D3 and Draak. Due to the use of hardcoded constants, they have no further (build) dependencies (obviously there is a runtime dependency).
- The last two patches replace the hardcoded constants by symbols from DT binding headers, and thus depend on those headers. Hence it should be postponed to v4.15.

For proper operation, this depends on the 3 series I have just sent:
- [PATCH 0/3] arm64: renesas: Base R-Car D3 support,
- [PATCH 0/4] soc: renesas: Add R-Car D3 support,
- [PATCH 0/4] clk: renesas: Add R-Car D3 support.

For testing, an integration branch containing all dependencies (and a few DT binding updates I do not want to send before "ARM: shmobile:
Document R-Car D3 SoC DT bindings" has been accepted) is available in the topic/r8a77995-integration branch of the git repository at
https://git.kernel.org/cgit/linux/kernel/git/geert/renesas-drivers.git.

Thanks for your comments!

To avoid dependencies on dt-binding headers going in through different paths, clock and power domain indices use hardcoded numbers.

This patch series adds minimal support for the R-Car D3 SoC and the Draak development board, allowing to boot from a ramdisk using a serial console.
- The first two patches add DT sources for R-Car D3 and Draak. Due to the use of hardcoded constants, they have no further (build) dependencies (obviously there is a runtime dependency).
- The last two patches replace the hardcoded constants by symbols from DT binding headers, and thus depend on those headers. Hence it should be postponed to v4.15.

For proper operation, this depends on the 3 series I have just sent:
- [PATCH 0/3] arm64: renesas: Base R-Car D3 support,
I have applied the above patchset for v4.14.
Quoted 1 line
- [PATCH 0/4] soc: renesas: Add R-Car D3 support,
And this one too.

Quoted 1 line
- [PATCH 0/4] clk: renesas: Add R-Car D3 support.
And this one seems to have been acked, so I assume you will apply it once you are back from holidays.
So I have applied the first two patches for v4.14.
Please repost the remaining two after v4.13-rc6 at which time I should be able to queue them up for v4.15.

I have now done so.
