dice: Add support for duplex streams with synchronization

This commit adds support for AMDTP in-stream. As a result, Dice driver
supports full duplex streams with synchronization.

When Dice chipset is 'enabled', it starts stream with correct settings.
And 'enabling' is global setting. So, when a stream is running, an opposite
stream can't start unless turning off 'enabling'. So a pair of streams must
be running. This is a loss of CPU usage when single stream is required.

Currently, sampling clock source is restricted to SYT-Match mode. This is
improved in followed commit. I note that at SYT-Match mode, Dice can select
from 4 streams for synchronization but this driver just uses the 1st stream
for simplicity.

dice: Support for non SYT-Match sampling clock source mode

This commit allows another mode.

When sampling clock source is SYT-Match mode, devices handle
'presentation timestamp' in received packets and generates sampling clock
according to the information. In this case, driver is synchronization master
and must transfer correct value in SYT field of each packets in outgoing
stream, then the outgoing stream is a master stream.

On the other hand, non SYT-Match mode, devices do this. So drivers must pick
up the value in SYT field of incoming packets and use the value for outgoing
stream.

dice: Add support for PCM capture

This commit adds a support for PCM capture.

When source of clock is external or opposite PCM substream is already running,
available sampling rate is limited at current one.

This driver give no way to change source of clock because it can be implemented
in user-land.

dice: Add support for MIDI capture/playback

This commit adds a support for MIDI capture/playback

When MIDI substrams already start streaming and PCM substreams are going to
join at different sampling rate, streams are stopped once. Then sampling rate
is changed and streams are restarted.

firewire-lib: Add sorting in-packets for full duplex streams with sync

In full duplex streams with synchronization, consistency of SYT field in
in-packets is important for out-packets. This commit add sorting in-packets
according to the value of dbc.
