The USB layer uses tty_hangup to deal with unplugs of the physical hardware
(analogous to loss of carrier) and then frees the resources. However the
tty_hangup is asynchronous. As the hangup can sleep we can use tty_vhangup
which is the non async version to avoid freeing resources too early.

This patch updates the r8a66597-udc buffer management code.

Use fixed buffers for bulk and isochronous pipes, also make
sure to handle the isochronous-as-bulk case. With fixed buffers
there is no need to keep track of used buffers with bi_bufnum.

Also, this fixes a potential buffer offset problem where the
base offset incorrectly varies with the number of pipes used.

Instead of a large (physically) linear buffer, we generate a set of
paged sk_buff, so no extra memory copy is involved. This removes
high-order allocations and saves quite a bit of memory. Phonet MTU is
65541 bytes, so the two buffers were padded to 128 kilo-bytes each.
Now, we create 17 page buffers, almost a 75% memory use reduction.

This patch (as1273) fixes two(!) bugs introduced by the new
Clear-TT-Buffer implementation in ehci-hcd.

	It is now possible for an idle QH to have some URBs on its
	queue -- this will happen if a Clear-TT-Buffer is pending for
	the QH's endpoint.  Consequently we should not issue a warning
	when someone tries to unlink an URB from an idle QH; instead
	we should process the request immediately.

	The refcounts for QHs could get messed up, because
	submit_async() would increment the refcount when calling
	qh_link_async() and qh_link_async() would then refuse to link
	the QH into the schedule if a Clear-TT-Buffer was pending.
	Instead we should increment the refcount only when the QH
	actually is added to the schedule.  The current code tries to
	be clever by leaving the refcount alone if an unlink is
	immediately followed by a relink; the patch changes this to an
	unconditional decrement and increment (although they occur in
	the opposite order).

Make sure the xHCI output device context is 64-byte aligned.  Previous
code was using the same structure for both the output device context and
the input control context.  Since the structure had 32 bytes of flags
before the device context, the output device context wouldn't be 64-byte
aligned.  Define a new structure to use for the output device context and
clean up the debugging for these two structures.

The copy of the device context in the input control context does *not*
need to be 64-byte aligned.

The xHCI host controller can be programmed to retry a transfer a certain number
of times per endpoint before it passes back an error condition to the host
controller driver.  The xHC will return an error code when the error count
transitions from 1 to 0.  Programming an error count of 3 means the xHC tries
the transfer 3 times, programming it with a 1 means it tries to transfer once,
and programming it with 0 means the HW tries the transfer infinitely.

We want isochronous transfers to only be tried once, so set the error count to
one.
