Vinod Koul d39513f851 ALSA: HDAC: move SND_HDA_PREALLOC_SIZE to core
Since this is common option for HDA driver to specfiy pre-allocated
buffer, we should make this option availble to all HDA driver by
moving this to HDA core

default 64
help
Specifies the default pre-allocated buffer-size in kB for the
HD-audio driver. A larger buffer (e.g. 2048) is preferred
for systems using PulseAudio. The default 64 is chosen just
for compatibility reasons.
Note that the pre-allocation size can be changed dynamically
via a proc file (/proc/asound/card*/pcm*/sub*/prealloc), too.
