These are used nowhere in the tree (except for some architectures which
define them for their own use) and were already removed in:
commit 6474924e2b5d ("arch: remove unused macro/function thread_saved_pc()")
commit c17c02040bf0 ("arch: remove unused *_segments() macros/functions")
Remove them from arch/csky as well.
