After the commit "a399dc9fc50 cpufreq: shmobile: Use generic platdev
driver", will use cpufreq-dt-platdev driver to enable cpufreq-dt support.
Hence, follow the implementation to support new R8A7795 SoC.

Well, you could have done that in the same patch. But I don't mind two patches
now.

Has it been finalized? Yeah, that would be preferred. -- viresh

Quoting Viresh when this file was introduced:
| This is going to be done once per boot and this shouldn't hurt. And for new

opp-v2 bindings.
As r8a7795/r8a7796 are not arm32 "shmobile", but arm64, perhaps we should
use this new "opp-v2" binding instead? Has it been finalized?
Thanks!
Gr{oetje,eeting}s,
