R-Car E3 (a.k.a. r8a77990) comes with the DAB hardware accelerator.
This patch adds SoC specific support.

We often express the first cell as just 0.

			reg = <0 0xe6730000 0 0x120>;

As the clock isn't documented in the documentation, I can't verify this
of the resets property :-S

I'll comment on the clock name in the DT bindings.
