pxa2xx_i2c_init() creates a pxa2xx-i2c-slave device on a second i2c-bus,
which has a NULL parent device. This causes an assertion in
object_get_canonical_path() when accessing pxa2xx-i2c-slave's
"parent_bus" link<bus> property in tosa and likely other PXA2xx machines.
Fix this by using the pxa2xx_i2c device, created just before, as parent.

Analogously to other NICs, we have to inform the network layer when
the can_receive handler will no longer report 0. Without this, we may
get stuck waiting on queued incoming packets.

i82378: Cleanup implementation
pci-host/prep: Set isa_mem_base in the PCI host bridge
In virtio_9p_device_init() there are 6x goto out that will lead to
v9fs_path_free() attempting to free unitialized path.data field.
Easiest way to trigger is: qemu-system-x86_64 -device virtio-9p-pci
Fix this by moving v9fs_path_init() before any goto out.

Guest trying to reset a endpoint of a disconnected device resulted in
xhci trying to dereference uport while being NULL, thereby crashing
qemu. Fix that by adding a check. Drop unused dev variable while
touching that code bit.

- 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

Current hcd-ohci does not handle DMA errors. However they may happen
so here we introduce simple error handling.
On such errors, a typical OHCI will stop operating, signal the guest
about the error by sending "UnrecoverableError Event", set itself into
error state and set "Detected Parity Error" in its PCI config space
to signal that it got an error and so does the patch.
This also adds ohci_die() call to ohci_bus_start() to handle possible
failure of qemu_new_timer_ns().

It turns out that some 32 bit windows guests crash
if 64 bit PCI hole size is >2G.
Limit it to 2G for piix and q35 by default.
User may override default 64-bit PCI hole size by
using "pci-hole64-size" property.
Examples:
-global i440FX-pcihost.pci-hole64-size=4G
-global q35-pcihost.pci-hole64-size=4G
