Add separate detach callback to USBPortOps, split
uhci/ohci/musb/usbhub attach functions into two.
Move common code to the usb_attach() function, only
the hardware-specific bits remain in the attach/detach
callbacks.
Keep track of the port it is attached to for each usb device.

This patch replaces explicit bswaps with endianness hints to the

Because we don't depend on the target endianness anymore, we can also
move the driver over to Makefile.objs.

As stated before, devices can be little, big or native endian. The
target endianness is not of their concern, so we need to push things
down a level.
This patch adds a parameter to cpu_register_io_memory that allows a
device to choose its endianness. For now, all devices simply choose
native endian, because that's the same behavior as before.

There is absolutely no need to call reset functions when initializing
devices. Since we are already registering them, calling qemu_system_reset()
should suffice. Actually, it is what happens when we reboot the machine,
and using the same process instead of a special case semantics will even
allow us to find bugs easier.
Furthermore, the fact that we initialize things like the cpu quite early,
leads to the need to introduce synchronization stuff like qemu_system_cond.
This patch removes it entirely. All we need to do is call qemu_system_reset()
only when we're already sure the system is up and running
I tested it with qemu (with and without io-thread) and qemu-kvm, and it
seems to be doing okay - although qemu-kvm uses a slightly different patch.
[ v2: user mode still needs cpu_reset, so put it in ifdef. ]
[ v3: leave qemu_system_cond for now. ]

You can add a OHCI USB Controller to your virtual pc now using

Add the parameter 'order' to qemu_register_reset and sort callbacks on
registration. On system reset, callbacks with lower order will be
invoked before those with higher order. Update all existing users to the
standard order 0.
Note: At least for x86, the existing users seem to assume that handlers
are called in their registration order. Therefore, the patch preserves
this property. If someone feels bored, (s)he could try to identify this
dependency and express it properly on callback registration.

It makes usb keyboard available for sh4/r2d system emulation.
The changes for "hw/usb-ohci.c" are as follows.
- 'localmem_base' is introduced as OHCIState struct member.
SM501 has a local memory, and it is used to pass and receive data with
OHCI driver. OHCI driver accesses it with SH4 physical memory address,
and SM501 accesses it with SM501 local address. 'localmem_base' holds
where the SM501 local memory is mapped into SH4 physical address space.
- Memory access functions modified to adjust address with 'localmem_base'.
The functions are, ohci_read_*(), ohci_put_*(), and ohci_copy_*().
- ohci_read_hcca() and ohci_put_hcca() are introduced for more consistent
implementation.
For other source files, it does,
- introduces usb_ohci_init_sm501().
- adds irq argument for SM501 initialization, to emulate USB interrupts.
