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!
