[v2,1/2] dt-bindings: clock: add R8A77970 CPG core clock definitions

Commit Message

Add macros usable by the device tree sources to reference the R8A77970
CPG core clocks by index. The data come from the table 8.2c of R-Car
Series, 3rd Generation User's Manual: Hardware (Rev. 0.55, Jun. 30, 2017).

Based on the original (and large) patch by Daisuke Matsushita
<[e-mail]>.

Changed in version 2:
- changed R8A7797 to R8A77970 everywhere;
- removed the CSIREF clock (renumbering the clocks that followed it);
- added the R-Car gen3 manual reference to the patch description;
- added Geert's tag;
- added Cogent Embedded's copyright;
- renamed the patch.

In personal conversations with technical people, I call myself a hacker. But
when I'm talking to journalists I just say "programmer" or something like that.
