Subject: powerpc: Kconfig: remove tautology in CONFIG_COMPAT
Date: Thu, 25 Jan 2024 15:55:12 -0700

This reverts commit 6fcb574125e6 ("powerpc: Kconfig: disable
CONFIG_COMPAT for clang < 12").

Now that the minimum supported version of LLVM for building the kernel has
been bumped to 13.0.1, this condition is always true, as the build will
fail during the configuration stage for older LLVM versions.  Remove it.
