CRAS: alsa_io - Set severe underrun threshold to five seconds
As explained in the issue, severe underrun is only targeted for special
case where bad dma driver makes hw_ptr jumps by a large distance and
creates a severe underrun that can not be recovered by filling blocks of
zeros. It should not be easily triggered by normal underrun or stressing
system.
BUG=chrome-os-partner:60497, chromium:662786
TEST=run balloon test in issue 60497, should not see resetting device.
