The `Functional` property means if a FRU is functional or not, e.g. if a DIMM
is plugged but has problem, it will be garded. At that time, the DIMM is
`Present`, but not `Functional`.

For this case, I think the test code shall be updated to skip the checks for
Functional, Version on specific FRU items.

Ping @Sivas again for comment.
