clang: Fix warnings in ARM GCS ACLE header

[des]

Summary

Including <arm_acle.h> in C code compiled with -Wstrict-prototypes
results in warnings (or errors if -Werror is in effect) due to missing
parameter lists for gcspr() and gcspopm().

Submitted upstream as PR#242286.

LGTM.

I thought we generally want to upstream patches to LLVM first and only once it's done backport them? If that is not necessary, I have some patches for LLVM that are waiting for upstream review and could be put to src.

Generally yes, we would have patches vetted by upstream first. Unless it is very urgent, or as in this case trivial, I don't think upstream will change anything here.

The issue is moot since the PR has been merged :)
