x86: remove always-defined CONFIG_AS_CFI
CONFIG_AS_CFI was introduced by commit e2414910f212 ("[PATCH] x86:
Detect CFI support in the assembler at runtime"), and extended by
commit f0f12d85af85 ("x86_64: Check for .cfi_rel_offset in CFI probe").
We raise the minimal supported binutils version from time to time.
The last bump was commit 1fb12b35e5ff ("kbuild: Raise the minimum
required binutils version to 2.21").
I confirmed the code in $(call as-instr,...) can be assembled by the
binutils 2.21 assembler and also by LLVM integrated assembler.
Remove CONFIG_AS_CFI, which is always defined.
