3a21532626 ehci: adaptive wakeup rate.
Adapt the frame timer sleeps according to the actual needs.  With the
periodic schedule being active we'll have to wakeup 1000 times per
second and go check for work.  In case only the async schedule is active
we can be more lazy though.  When idle ehci will increate the sleep time
step by step, so qemu has to wake up less frequently.  When we'll see
transactions on the bus or the guest fiddles with the schedule
enable/disable bits we'll return to a 1000 Hz wakeup rate and full
speed.  With both schedules disabled we stop wakeups altogether.

This patch also drops the freq property (configures wakeup rate
manually) which is obsoleted by this patch.

daf25307b4 ehci: fix halt status handling
When the enable bits for controller / async schedule / periodic schedule
change just make sure we kick the frame timer and let
ehci_advance_periodic_state and ehci_advance_async_state handle the
controller state changes.

This will make ehci set USBSTS_HALT when the controller shutdown is
actually done, once both schedules are in inactive state and the
USBSTS_PSS and USBSTS_ASS bits are clear.

18eef3bc4e scsi: prepare migration code for usb-storage support
usb-storage can't handle requests in one go as the data transfer can be
splitted into lots of usb packets.  Because of that there can be
normal in-flight requests at savevm time and we need to handle that.
With other scsi hba's this happens only in case i/o is stopped due to
errors and there are pending requests which need to be restarted
(req->retry = true).

So, first we need to save req->retry and then handle the req->retry =
false case.  Write requests are handled fine already.  For read requests
we have to save the buffer as we will not restart the request (and thus
not refill the buffer) on the target host.

In commit 1bba0dc932 cpu_reset()
was renamed to cpu_state_reset(), to allow introducing a new cpu_reset()

All callers have been updated except for one in target-mips, so drop all
implementations except for the one in target-mips and move the
declaration there until MIPSCPU reset can be fully QOM'ified.
