Takashi Iwai 675f25d4d3 ALSA: hda - Add bdl_pos_adj option 
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.
