dt-bindings: fuse: Move renesas,rcar-{efuse,otp} to nvmem 



The R-Car E-FUSE blocks can be modelled better using the nvmem
framework.

Replace the R-Car V3U example by an R-Car S4-8 ES1.2 example, to show
the definition of nvmem cells.  While at it, drop unneeded labels from
the examples, and fix indentation.

Add an entry to the MAINTAINERS file.
