piix3 piix4: Clean up use of cannot_instantiate_with_device_add_yet
A PIIX3/PIIX4 southbridge has multiple functions. We model each
function as a separate qdev. Two of them need some special wiring set
up in pc_init1() or mips_malta_init() to work: the ISA bridge at 01.0,
and the SMBus controller at 01.3.
The IDE controller at 01.1 (piix3-ide, piix3-ide-xen, piix4-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.
