Subject: [PATCH] uprobes: remove function declarations from arch/{mips,s390}

The declarations of arch-specific functions have been moved to a common
header in commit 3820b4d2789f ('uprobes: Move function declarations out of
arch'), but MIPS and S390 has added them to their own trees later.
Remove the unnecessary duplicates.
