flash: Introduce flash_validate()

Clean up the protocol_negotiate_version() mess. The existing approach
came about due to viewing the vpnor implementation as an edge case in
its own right. The code becomes much neater if we consider all backends
as equal and afford them the callbacks necessary for correct behaviour.
