ALSA: hda - Provide missing pin configs for VAIO with ALC260

Some models (or maybe depending on BIOS version) of Sony VAIO with
ALC260 give no proper pin configurations as default, resulting in the
non-working speaker, etc.  Just provide the whole pin configurations

ALSA: firewire-lib: fix wrong value for FDF field as an empty packet

This commit fix out of specification about the value of FDF field in out packet
with 'no data'. This affects blocking mode.

According to IEC 61883-6, there is two way to generate AMDTP packets include no
data in blocking mode.

Way 1. an empty packet defined in IEC 61883-1
 - Size of packet is 2 quadlets.
 - The value of FDF is sfc.
 - The packet includes only CIP headers

Way 2. a special non-empty packet defined in IEC 61883-6
 - Size of packet is following to blocking mode
 - The value of FDF is 0xff. This value is 'NO-DATA'. This means 'The receiver'
   must ignore all the data in a CIP with this FDF code'.
 - The packet includes dummy data.

But current implementation is a combination of them.
 - Size of packet is 2 (way 1)
 - FDF = 0xff (way 2)
This causes BeBoB chipset cannot sound.

This patch applies Way 1.

firewire-lib: Add support for MIDI capture/playback

For capturing/playbacking MIDI message, this commit adds the functionality to
multiplex/demultiplex MIDI messages into AMDTP sream in IEC 61883-6. As a
result, the number of MIDI ports is limited by 16 ports, for my convinience.

And this commit allows to set PCM format even if AMDTP stream already starts.
I suppose the case that PCM data starts to be multiplexed/demultiplexed after
AMDTP stream is already started for MIDI. To distinguish whether PCM or MIDI
functionality starts AMDTP stream, this commit adds amdtp_stream_pcm_running()
and amdtp_stream_midi_running(). I think this is better than reference-counter.

IEC 61883-6 refers to AMEI/MMA RP-027 for implementation of MIDI conformant
data. In the specification, 'MIDI1.0-2x/3x-SPEED' mode are described with
'negotiation procedure' and 'encapsulation details'. But there is no
specifications to define them. This module implement 'MIDI1.0-1x-SPEED' mode.

firewire-lib: Add support for duplex streams synchronization in blocking mode

Generally, the devices can synchronize to handle 'presentation timestamp'
in CIP packets. This commit adds the functionality to pick up this timestamp
from in-packets transmitted by the device, then use it for out packets.

In previous implementation, this module generated the timestamp by itself. This
is 'SYT Match' mode. Then it acts as synchronization master. This commit allows
this module to act as synchronization slave.

This commit restricts this mechanism is only available in blocking mode because
handling the timestamp in non-blocking mode is more complicated than in
blocking mode.

firewire-lib: Add transfer delay to synchronized duplex streams

Currently, when duplex streams with synchronization mode, this module just pass
'presentation timestamp' from transmitted packets to out packets. This is
enough to handle actual device but logically it should include 'transfer delay'
and 'processing time'. This means the timestamp in out packet should be at
future.

To be simple, this commit add only 'transfer delay'.
