This makes the mem MemoryRegion available to derived instance_inits.
Keep the bus in realize for now since naming breaks in instance_init.

The SysBus qdev initfn merely calls SysBusDeviceClass::init, so we can
replace it with a realizefn already. This avoids getting into any initfn
ambiguity with the upcoming Faraday EHCI implementation.
Rename internal usb_ehci_initfn() to usb_ehci_realize() to allow to
return Errors from common initialization code as well.

The DMAContext is a simple pointer to an AddressSpace that is now always
already available. Make everyone hold the address space directly,
and clean up the DMA API to use the AddressSpace directly.

SysBus EHCI was introduced in a hurry before 1.3 Soft Freeze.
To use QOM casts in place of DO_UPCAST() / FROM_SYSBUS(), we need an
identifying type. Introduce generic abstract base types for PCI and
SysBus EHCI to allow multiple types to access the shared fields.
While at it, move the state structs being amended with macros to the
header file so that they can be embedded.
The VMSTATE_PCI_DEVICE() macro does not play nice with the QOM
parent_obj naming convention, so defer that cleanup.

Hotplugging them simply doesn't work, so tag them accordingly to
avoid users trying and then crashing qemu.
For xhci there is nothing fundamental which prevents hotplug from
working, we'll "only" need a exit() function which cleans up
everything properly. That isn't for 1.3 though.
For ehci+uhci+ohci hotplug can't be supported until qemu gains the
capability to hotplug multifunction pci devices.

Starting with commit 1c380f9460 dma
transfers can actually fail. This patch makes ehci keep track
of the busmaster bit in pci config space, by setting/clearing the
dma_context pointer. Attempts to dma without context will result
in raising HSE (Host System Error) interrupt and stopping the host
controller.
This patch fixes WinXP not booting with a usb stick attached to ehci.
Root cause is seabios activating ehci so you can boot from the stick,
and WinXP clearing the busmaster bit before resetting the host
controller, leading to ehci actually trying dma while it is disabled.
