Use schedule_timeout_{,un}interruptible() instead of
set_current_state()/schedule_timeout() to reduce kernel size.  Also use
human-time conversion functions instead of hard-coded division to avoid
rounding issues.

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
interrupt frequency cannot be higher, and clients that would try to
use 96 kHz would run at half their desired speed.
Signed-off-by: NClemens Ladisch <clemens@ladisch.de>

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.
