Not all devices with ACPI and this combination of sound devices will
have the required information provided via ACPI.  Reintroduce the I2C
device ID to restore sound functionality on on the Chromebook 'Samus'
model.

This is a regression from v4.12 on my laptop (a Chromebook 'Samus'
that's not running ChromeOS).  My fault for getting out of the habit of
trying -rc1 when it comes out and not spotting this sooner.  I'm not
100% sure if this fix is correct for all cases as I'm only able to test
my hardware here, and this does fix my laptop.
