pc_piix: remove pc-i440fx-1.4 up to pc-i440fx-1.7 

These are the last users of the 128K SeaBIOS blob in the i440FX family.
Removing them allows us to drop PCI support from the 128K blob,
thus making it easier to update SeaBIOS to newer versions.

@ -277,14 +277,6 @@ deprecated; use the new name ``dtb-randomness`` instead. The new name
better reflects the way this property affects all random data within

These old machine types are quite neglected nowadays and thus might have
various pitfalls with regards to live migration. Use a newer machine type
instead.
