Ok so, this patch was really just going to slightly align the
configuration with the STE driver.  I'll drop it and just fix the wrong
comment as a trivial patch.

For the reimplementation with channel configuration from machine driver,
I actually went through that, but was not able to find the reason why
there is a slot offset somewhere (example: I request 0x0001 for first
slot on the DAI and that shows up on slot 8 on the codec), so I just
updated the hardcoded value.  I'll try to get some explanation for that.
