cpu/x86/smm: Fix explicit 'addr32' usage in clang builds
The addr32 prefix is required by binutils, because even when
given an explicit address which is greater than 64KiB, it will
throw a warning about truncation, and stupidly emit the opcode
with a 16-bit addressing mode and the wrong address.
However, in the case of LLVM, this doesn't happen, and is happy
to just use 32-bit addressing whenever it may require it. This
means that LLVM never really needs an explicit addr32 prefix to
use 32-bit addressing in 16-bit mode.
