archs38: Merge sd and ramfs subtargets in generic again
As it turned out we may actually build both initramfs and SD-based images in one run with just a small tweak in existing image/Makefile and so we do here. We're back with one "generic" target for all ARC HS38-based bords. Kudos to John for his patience and very helpful tips!
