A VT82C686B southbridge has multiple functions. We model each
function as a separate qdev. One of them need some special wiring set
up in mips_fulong2e_init() to work: the ISA bridge at 05.0.
The IDE controller at 05.1 (via-ide) has always had
cannot_instantiate_with_device_add_yet set, but there is no obvious
reason why device_add could not work for them. Drop it.
