[v2,1/5] q35: Remove old machine versions

Commit Message

Eduardo Habkost Jan. 23, 2016, 4:02 p.m. UTC

Migration with q35 was not possible before commit
04329029a8c539eb5f75dcb6d8b016f0c53a031a, because q35
unconditionally creates an ich9-ahci device, that was marked as
unmigratable. So all q35 machine classes before pc-q35-2.4 were
not migratable, so there's no point in keeping compatibility code
for them.

Remove all old pc-q35 machine classes and keep only pc-q35-2.4
and newer.
