ARM: remove Thumb2 __builtin_thread_pointer workaround for Clang

Now that the minimum supported version of LLVM for building the kernel has
been bumped to 13.0.1, the conditional expression added to get_current()
by commit c1e42efacb9b ("ARM: 9151/1: Thumb2: avoid
__builtin_thread_pointer() on Clang") is always true, as the build will
fail during the configuration stage for older LLVM versions.  Remove it,
effectively reverting the aforementioned change.
