I got the logic wrong in the DT CPU features code when I added the
Power9 DD2.1 feature. We should be setting the bit if we detect a
DD2.1, not clearing it if we detect a DD2.0.
This code isn't actually exercised at the moment so nothing is
actually broken.

There was a breakage in the kernel ABI, and the old petitboot

This format is similar to existing SNDRV_PCM_FORMAT_{S,U}20_3 that keep
20-bit PCM samples in 3 bytes, however i.MX6 platform SSI FIFO does not
allow 3-byte accesses (including DMA) so a 4-byte format is needed for it.

This problem has been traced to silicon errata ERR003778:

Not sure how I missed that. Thanks for catching this Fred. I have sent a
