How about moving that to setup-rcar-gen2.c instead ? There's nothing specific 
to r8a7793 here. We could even introduce a "renesas,rcar-gen2" DT compatible 
entry and match on that instead of "renesas,r8a7793" (which should of course 
be specified as well in DT). You could also add "renesas,r8a7794" to the 
setup-rcar-gen2.c compat list and remove setup-r8a7794.c.
