After bus reset, isochronous resource manager releases all of allocated
isochronous resources. The nodes to restart packet streaming should
request reallocation of the resources.
However, between the bus-reset and invocation of 'struct fw_driver.update'
handler, ALSA PCM application can detect this situation by XRUN because
the target device cancelled to transmit packets once bus-reset occurs.
Due to the above mechanism, ALSA firewire-tascam driver just stops
packet streaming in the update handler, thus pcm.prepare handler
should request the reallocation.
This commit requests the reallocation in pcm.prepare callback when
bus generation is changed.

Once allocated, isochronous resources are available for packet
streaming, even if the streaming is cancelled. For this reason,
current implementation handles allocation of the resources and
starting packet streaming at the same time. However, this brings
complicated procedure to start packet streaming.
This commit separates the allocation and starting. The allocation is
done in pcm.hw_params callback and available till pcm.hw_free callback.
Even if any XRUN occurs, pcm.prepare callback is done to restart
packet streaming for allocated the resources.
There are two points to stop packet streaming; in pcm.hw_params and
pcm.prepare callbacks.

Variax driver had a very complex and staged startup sequence using
multiple timers and a work. This patch simplifies the procedure to a
single delayed work.
Now the startup stage consists of:
- VARIAX_STARTUP_VERSIONREQ:
requesting the version and the message handler raises up to the next
stage upon receiving the reply. The request is repeated until a
reply arrives.
- VARIAX_STARTUP_ACTIVATE:
does activation, and queue for the next stage.
- VARIAX_STARTUP_SETUP:
registers the card.

The current code performs the cancel of a delayed work at the late
stage of disconnection procedure, which may lead to the access to the
already cleared state.
This patch assures to call cancel_delayed_work_sync() at the beginning
of the disconnection procedure for avoiding that race. The delayed
work object is now assigned in the common line6 object instead of its
derivative, so that we can call cancel_delayed_work_sync().
Along with the change, the startup function is called via the new
callback instead. This will make it easier to port other LINE6
drivers to use the delayed work for startup in later patches.

By taking into account the mapping from logical to DMA channels when

HDSPe AIO card are now correctly captured and played back in single speed
mode.
Since the mapping is an identity mapping for all cards except AIO and
RayDAT, only those cards should be affected by this patch. It was tested on
an AIO card. The patch needs testing on other cards, in particular RayDAT.
Note: this patch does not solve ADAT capture and playback issues in double
