[phosphor-ipmi-host] static assertion be raised in aarch64 build

[CHLI30 at nuvoton.com]

Hi All,
Is anyone meet this kind of static_assert() be raised in "pack.hpp" and "unpack.hpp"?

We meet one compile error in "aarch64" platform with the newer commit (5d38067).
However, the same commit without this compile error in "arm" platform.
I try to diff "arm" and "aarch64" compile options,
Unfortunately, didn't find any clues to fix this build error in aarch64 platform.

Error message of log.do_compile:
error: static assertion failed: Attempt to pack a type that has no IPMI unpack operation
error: static assertion failed: Attempt to unpack a type that has no IPMI unpack operation
