[ALSA] hda-intel - Fix HDA buffer alignment

From the HDA spec it appears that the buffers written to the BDL and
sent to a codec must be 128 byte aligned (section 4.5.1).  The alignment
was not happening especially when playing 6 channels.  This patch set
the alignment of buffers and periods to 128 bytes.
