Add support for R-Car M3-N (r8a77965) power areas and reset.
M3-N power areas are identical to M3-W ones, so just copy and rename
them.

They are not identical:
  - M3-N does not have the CA53-related areas,
  - M3-W does not have A3VP,
  - M3-N does not have A2VC0 (M3-W also doesn't, according to latest
datasheet?).

The datasheet also mentions A3SH, without further info about the register
block. I think we need to bring this up with Renesas.

The maintainer may ask you to split this patch by functionality...

Yes, I would like this split up.

I think "[PATCH 00/11] Add R8A77980/Condor board support" provides
a good example.
