ich9: Document why cannot_instantiate_with_device_add_yet

An ICH9 southbridge contains several PCI devices, some of them with
multiple functions. We model each function as a separate qdev. Two
of them need some special wiring set up in pc_q35_init() to work: the...

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,...

vt82c686: Clean up use of cannot_instantiate_with_device_add_yet

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....

qdev: Replace no_user by cannot_instantiate_with_device_add_yet

In an ideal world, machines can be built by wiring devices together
with configuration, not code. Unfortunately, that's not the world we
live in right now. We still have quite a few devices that need to be...

sysbus: Set cannot_instantiate_with_device_add_yet

device_add plugs devices into suitable bus. For "real" buses, that
actually connects the device. For sysbus, the connections need to be
made separately, and device_add can't do that. The device would be...

ich9: APIs for pc guest info

This adds APIs that will be used to fill in
acpi tables, implemented using QOM,
to various ich9 components.
Some information is still missing in QOM,
so we fall back on lookups by type instead.

hw: set interrupts using pci irq wrappers

pci_set_irq and the other pci irq wrappers use
PCI_INTERRUPT_PIN config register to compute device
INTx pin to assert/deassert.

An irq is allocated using pci_allocate_irq wrapper
only if is needed by non pci devices....

i82378: Cleanup implementation

- i82378 only exists on PCI bus; do not split implementation in 2 structs
- remove BARs, which are not specified in datasheet
- replace custom isa_mmio implementation by PCI bus IO region usage
- use QOM casts when required...

pci-host/prep: Set isa_mem_base in the PCI host bridge

Currently, it is done by i82378 PCI-ISA bridge, which shouldn't
care about it.
