[PATCH 02/14] security/Kconfig.hardening: Remove tautological condition from CC_HAS_ZERO_CALL_USED_REGS

Now that the minimum supported version of LLVM for building the kernel
has been raised to 17.0.1, the '!Clang || Clang > 15.0.6' dependency for
CONFIG_CC_HAS_ZERO_CALL_USED_REGS is always true, so it can be removed.
