Up until now there was no need in those stubs.

But since following commit compilation of U-Boot on ARC is broken: commit 7861204c9af7fec1ea9b41541c272516235a6c93 itest: make memory access work under sandbox

That's because CMD_ITEST is enabled by default in common/Kconfig and now map_physmem()/unmap_physmem() is used there.

So this patch adds missing stubs for ARC.

This looks OK, but rather than cut/pasting this exact same code yet another time, why not create e.g. include/io-base.h that contains this, and share it amongst all architectures?
