ATI SB controllers seem to report the DMA ahead in the amount of FIFO.
Thus bdl_pos_adj should be 32 for them as default.

Also, the default value is set to -1, which means to make the driver
to choose the appropriate value.

The option bdl_pos_adj should be provided for each card instance instead of

position_fix=3 is the option to correct the DMA position with the
FIFO size.  But, it never worked correctly, and we have now more other
workarounds for the DMA position fixes.  Thus better to remove it.

Also, change POS_FIX_NONE to POS_FIX_LPIB to represent its real role
better.

Added a new option, bdl_pos_adj, to adjust the delay of IRQ-wakeup
timing.

Most HD-audio hardwares have a problem that a BDL IRQ is issued before
actually the data and the DMA pointer are updated.
We have already a mechanism to force to delay snd_pcm_period_elapsed()
calls via workq, but this costs much CPU, and typically the delay is
within one sample.  Thus, it's more clever to adjust the BDL entries
instead.

The new option adds the size of the delay in frames.  As default,
it's set to 1 -- that is, one sample delay.  Even the hardware is
really correct, one sample delay is relatively harmless in comparison
with reporting wrong positions.

Many HD-audio controllers seem inaccurate about the IRQ timing of
PCM period updates.  This has caused problems on audio quality; e.g.
JACK doesn't work with two periods.

This patch fixes the problem by checking the current DMA position
at IRQ handler and delays the period-update via a workq if it's
inaccurate.

free_irq() calls synchronize_irq() for you, so there is no need for
drivers to manually do the same thing (again).  Thus, calls where
sync-irq immediately precedes free-irq can be simplified.

However, during this audit several bugs were noticed, where free-irq is
preceded by a "irq >= 0" check... but the sync-irq call is not covered
by the same check.

So, where sync-irq could not be eliminated completely, the missing check
was added.

In the current scheme, PCM device numbers are assigned incrementally
in the order of codecs.  This causes problems when the codec number
is irregular, e.g. codec #0 for HDMI and codec #1 for analog.  Then
the HDMI becomes the first PCM, which is picked up as the default
output device.  Unfortuantely this doesn't work well with normal
setups.

This patch introduced the fixed device numbers for the PCM types,
namely, analog, SPDIF, HDMI and modem.  The PCM devices are assigned
according to the corresponding PCM type.  After this patch, HDMI will
be always assigned to PCM #3, SPDIF to PCM #1, and the first analog
to PCM #0, etc.
