The bswap16 TCG opcode assumes that the high bytes of the temp equal
to 0 before calling it. The ARM backend implementation takes this
assumption to slightly optimize the generated code.
The same implementation is called for implementing the cross-endian
qemu_st16 opcode, where this assumption is not true anymore. One way to
fix that would be to zero the high bytes before calling it. Given the
store instruction just ignore them, it is possible to provide a slightly
more optimized version. With ARMv6+ the rev16 instruction does the work
correctly. For lower ARM versions the patch provides a version which
behaves correctly with non-zero high bytes, but fill them with junk.

The TCG arm backend considers likely that the offset to the TLB
entries does not exceed 12 bits for mem_index = 0. In practice this is
not true for at least the MIPS target.
The current patch fixes that by loading the bits 23-12 with a separate
instruction, and using loads with address writeback, independently of
the value of mem_idx. In total this allow a 24-bit offset, which is a
lot more than needed.

Instead report them as successfully completed directly on submission, this
has 2 advantages:
1) This matches the timing of interrupt output packets on real hardware,
with the previous async handling, if an ep has an interval of say 500 ms,
then there would be 500+ ms between the submission and the guest seeing the
completion, as we wont do the write back until the qh gets polled again. And
in the mean time the guest may very well have timed out, as the guest can
reasonable expect a much quicker completion.
2) This fixes interrupt output packets potentially getting send twice
surrounding a migration. As we delay the writeback to guest memory until
the qh gets polled again, there is a window between completion and writeback
where migration can happen, in this case the destination will not know
about the completion, and it will execute the packet *again*
But it does also come with a disadvantage:
1) If the actual interrupt out to the real usb device fails, there is no
way to report this back to the guest.
This patch assumes however that interrupt outs in practice never fail, as
they are only used by specialized drivers, which are unlikely to issue illegal
requests (unlike general class drivers which often issue requests which some
devices don't implement). And that thus the advantages outway the disadvantage.

It is possible for device disconnect and the guest trying to reset the port
(because of USB xact errors prior to the disconnect getting signaled) to race,
when we hit this race, the guest will write the port-control register with its

device with its port-enabled bit set in its port-control register, which
is no good :)

Add a completions_only flag, and set this when running process_frame for async
completion handling, this fixes 2 issues in a single patch:
1) It makes sure async completed packets get written to guest mem immediately,
even if all the bandwidth for the frame was consumed from the timer run
process_frame. This is necessary as delaying their writeback to the next frame
can cause the completion to get lost on migration.
2) The calling of process_frame from a bh on async completion causes iso
tds to get server more often they should, messing up usb sound class device
timing. By only processing completed packets, the iso tds get skipped fixing
this.
