No RISC-V-specific nodes need to be created at the moment,
so make_arch_nodes() is implemented to simply return 0.

Same question as on the previous patch, albeit to a lesser degree: An
arch hook may plausibly exist (and be called) uniformly, even if on
some arch-es it doesn't do anything.

Further, on what basis is this function put in this new file, when the
earlier ones live in domain-build.c?

obj-$(CONFIG_DOM0LESS_BOOT) += dom0less-build.init.o

just like Arm has it?
