ALSA: hda/intel: increase default bdl_pos_adj for Nvidia controllers
The default bdl_pos_adj of 32 for Nvidia HDA controllers is
insufficient on GA102 (and likely other recent Nvidia GPUs) after S3
suspend/resume. The controller's DMA timing degrades after resume,
causing premature IRQ detection in azx_position_ok() which results in
silent HDMI/DP audio output despite userspace reporting a valid
playback state and correct ELD data.
Increase bdl_pos_adj to 64 for AZX_DRIVER_NVIDIA, matching the value
already used by Intel Apollo Lake for the same class of timing issue.
