CRAS: alsa_io - Move volume curve to alsa output node

Currently if sound card doesn't have mixer control for 'Speaker', CRAS
won't associate the volume curve specified by [Speaker] label in card
config.
Fix this issue by moving volume curve from mixer control to alsa output
node.

BUG=chromium:682164
TEST=unittest. On platform without 'Speaker' control, verify volume
curve for speaker can be loaded.
