Convert loop.c from the deprecated kernel_thread to kthread. This patch
simplifies the code quite a bit and passes similar testing to the previous
submission on both emulated x86 and s390.
Changes since last submission:
switched to using a rather simple loop based on
wait_event_interruptible.

Change to a different ASF heartbeat message code to improve
reliability.
There were some reports of unintended resets on real time kernels
where the timer may be slow and cause the heartbeat to be late.
Netpoll will also have the same problem because the timer irq will
be unavailable.
Using the new heartbeat code, the ASF firmware will also check the
ring condition before resetting the chip when the heartbeat is
expiring.

This patch (as790b) adds "autostop" support to ohci-hcd: the driver

CONFIG_USB_SUSPEND hasn't been set.

The autosuspend technique used by ohci-hcd doesn't mesh well with the
newer USB core autosuspend code. This patch (as789) removes ohci-hcd's

automatically go into a low-power state when no devices are connected.

This patch (as787) creates a new workqueue thread to handle delayed
USB autosuspend requests. Previously the code used keventd. However
it turns out that the hub driver's suspend routine calls
flush_scheduled_work(), making it a poor candidate for running in
keventd (the call immediately deadlocks). The solution is to use a
new thread instead of keventd.
