This allows us to eliminate the casts in the drivers, and eventually
remove the use of the device_driver function pointer methods for
platform device drivers.

Introduce some sbus_dma routines similar to the

Modules: USB generic driver
If we submit all our URBs when a playback stream is started, the first
hwptr_done update for each URB happens at the same time. This results
in an underrun when there isn't enough PCM data available at this
point for all URBs.
To avoid this, we begin submitting our URBs earlier (when the stream
is prepared), with empy packets. When the stream is started, the
prepare_playback_urb() call for each URB will be run only when the
respective URB has completed previously, so the first hwptr_done
updates will be done nicely staggered.

Modules: AZT3328 driver
this is now an even much more reworked patch (#3) for my azt3328.c ALSA driver.
IOW I spent another 4 evenings to get the sequencer timer to work properly
(my head is still hurting) and do lots of other cleanups.
Note that despite the extensive sequencer timer additions, the driver object
is still only 2kB bigger than the previous version, due to those many
optimizations...
Changes in version #3:
- fully working ALSA sequencer timer support for the card's 1024000Hz
DirectX timer (downscaling adjustable via seqtimer_scaling module param)
- an insane amount of code optimizations
- many, many cleanups
Changes in version #2:
- FOUND the 1us DirectX timer area (yay!), made the code respect it
properly
- renamed some 'weird' mixer control names according to ControlNames.txt
- cleanup unneeded debug messages, reformatting
- improved I/O register documentation
- constified many more structs
Changes in version #1:
- improves/fixes some fatal playback/recording interaction
- improves IRQ handler performance (and actually fixes some weird code)
- coalesces some I/O accesses
- slightly improves I/O interface documentation
- improves/fixes logging
- defines out some less important debug code
- constifies some data

Modules: NM256 driver
The current snd-nm256 driver can cause Dell Latitude CSx laptops to
lock-up during module (un)load. I have isolated this to the writes to
the control port register at offset 0x6cc which were not already
protected by the existing reset_workaround.
I tried grouping these writes with the existing reset_workaround
clause, but that caused the driver to have (un)load problems on the
Dell Latitude LS laptops. So, I have implemented a reset_workaround_2
clause (please feel free to suggest a better name!) to cover this
situation and added a quirk entry for the CSx laptops.

Modules: YMFPCI driver
We better pretend that the ymfpci timer runs at 48 kHz because the

Modules: ALSA sequencer
When no default timer frequency has been set, initialize_timer() just
uses the maximum frequency supported by the timer, which is ridiculously
high on 96 kHz timers.
This patch introduces a default frequency of 1000 Hz for this case, and
makes sure that a frequency set by the user isn't too high.

Modules: VIA82xx driver
The change only affects the via823x kind of chips.
Here the via8233_pcm_pointer_hw() function
(named snd_via8233_pcm_pointer() before)
needed to loop until a non zero position is red from the chip.
Measurements have shown that more than 200 loops are typically needed on
an Athlon64.
As io-reads cost many cycles, those loops sum up huge.
via8233_pcm_pointer_hw() runs either in interrupt or with interrupts
disabled. So it introduces significant interrupt latency.
The patch introduces a calculated position value hwptr_done,
that is updated by the interrupt routine when a period is completed.
It is only used, if the 823x chip returns a zero position, which can't
be interpreted reliably.
Further optimisation is applied on the 8233 chip's interrupt routine:
Only the SGD_SHADOW is read, as it contains all infos needed.
We ommit ~5 more register reads that way.
