libflashrom: Drop querying functions

This implementation of querying functions has shown too many
maintainability issues and at the same time we couldn't find
any user of it. Questions on Gerrit and the ML [1] were left
unanswered.

Part of it was already removed, let's remove all of it to re-
duce the churn.
