ALSA: fireface: pick up time stamp for request subaction of asynchronous transaction

The time stamp of isochronous cycle at which asynchronous transaction is
sent is perhaps useful somehow. A commit b2405aa948b9 ("firewire: add
kernel API to access packet structure in request structure for AR context")
adds kernel API to retrieve the time stamp in inner structure of request
subaction.

This commit changes local framework to handle message delivered by the
asynchronous transaction so that time stamp is picked up by the kernel API.

ALSA: fireface: add support for RME Fireface UFX (untested)

Fireface UFX was shipped by RME GmbH in 2010, and now discontinued.
Although this model has some enhanced feature which Fireface 802
doesn't have (e.g. on-board USB mass storage device class, configuration
interface with color display), the functionality relevant to
packet communication on IEEE 1394 bus seems to be the same as
Fireface 802 (e.g. available number of channels for PCM frame in
each sampling transfer frequency).

With the assumption, this commit adds support for Fireface UFX. In ALSA
fireface driver, these two models are handled as the same one.

ALSA: fireface: add support for RME FireFace 802

Fireface 802 was shipped by RME GmbH in 2014. This model supports later
protocol for management of isochronous communication and synchronization
of sampling transmission frequency.

This model consists of below ICs:
* TI TSB41AB2
* Xilinx Spartan-6 FPGA XC6SLX16
* TI TMS320 C6747
* SMSC USB3250

Especially, this model just supports IEEE 1394a, against its name which
evokes Fireface 800.

This commit adds support for Fireface 802 (tested). Userspace applications
can transfer PCM frames and MIDI messages via ALSA PCM/Rawmidi interface.
I note that 4 channels for ADAt1 and ADAT2 are disabled at higher sampling
transfer frequency since isochronous resources reservation fails due to
bandwidth limitation of IEEE 1394a.

The value read from LATTER_SYNC_STATUS register is slightly different
from the one of Fireface UCX. The higher 4 bits and lower 4 bits are
swapped within the same byte.

Without any assist of userspace application, transmitted MIDI messages
from the device are not going to be processed. For detail, please refer
to my comment in code of latter protocol.

buffer size when another PCM substream starts, therefore the PCM
substream has a constraint to its buffer size.

ALSA: fireface: reserve/release isochronous resources in pcm.hw_params/hw_free callbacks

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.

ALSA: fireface: support rx MIDI functionality for Fireface UCX

In latter model of Fireface series, asynchronous transaction includes
a prefix byte to indicate the way to decode included MIDI bytes.

Upper 4 bits of the prefix byte indicates port number, and the rest 4
bits indicate the way to decode rest of bytes for MIDI messages.

Basically the rest bits indicates the number of bytes for MIDI message.
However, if the last byte of each MIDi message is included, the rest
bits are 0xf. For example:

message: f0 00 00 66 14 20 00 00 f7
offset: content (big endian, port 0)
'0030: 0x02f00000
'0030: 0x03006614
'0030: 0x03200000
'0030: 0x0ff70000

This commit supports encoding scheme for the above and allows
applications to transfer MIDI messages via ALSA rawmidi interface.
An unused member (running_status) is reused to keep state of
transmission of system exclusive messages.
