There is no driver to match these two channels, so
remove them. This fixes warnings from MHI subsystem during suspend:
mhi mhi0_LOOPBACK: 1: Failed to reset channel, still resetting
mhi mhi0_LOOPBACK: 0: Failed to reset channel, still resetting
This feels like just masking a real issue.
If LOOPBACK is not being consumed, then the channel should never go
into the start state. Why would we be trying to transition to the
reset state then?

That is because, with patch 'bus: mhi: host: add new interfaces to
handle MHI channels directly' in this patch set, ath11k is able to call
mhi_unprepare_all_from_transfer(), which will reset all channels.
that implementation is flawed if it is causing this. Looks like you
never check to see if the channel was prepared in the first place.
If you go fix that, then it looks like this change is not needed.
