ARM: S3C64XX: Fix fallthrough bug in i2sv3 gpio configuration, improve logging

If the platform device id is 1, the code will fallthrough the
case and incorrectly return -EINVAL. Add a break to avoid fallthrough.

Make logging slightly more verbose by including the device id.

This fixes an issue only present in multi-component.
