hal: Reduce the deep buffer period count.

-Deep buffer period count in the driver is 8. This adds to latency
 of 160ms. This also results in the common block to have 8 buffers.
-The total latency used for AV sync is 320ms. AV sync issues are
 seen due to this big latency
-Reduce the deep buffer cound from 8 to 4. This would reduce the
 latency.
