[PATCH] Revert "powerpc/xmon: Relax frame size for clang"

[ndesaulniers at google.com]

This reverts commit 9c87156cce5a63735d1218f0096a65c50a7a32aa.

I have not been able to reproduce the reported -Wframe-larger-than=
warning (or disassembly) with clang-11 or clang-18.

I don't know precisely when this was fixed in llvm, but it may be time
to revert this.
