google/reef: update timing of sdmode toggling
Maxim98357a speaker amp requires BCLK & SFRM to be active
and stable before it is unmuted. If there is a BLCK and no
SFRM, it results in a pop sound.
sdmode_delay property already exists which facilitates this
configuration. This patch updates "sdmode_delay" to avoid
pop sound.
BUG=chrome-os-partner:58356
BRANCH=None
TEST=while audio playback via headset, remove headset.
Audio will be switched playback to speaker. Observe if
pop sound comes from speaker.
