I think it could be better to insert these into the fsl-asoc-card.txt
without those redundant property descriptions. At least it should be
added to the compatible list. And you may add a comment in (...) to
describe that it supports both 4271 and 4272.

These two properties are missing in the fsl-asoc-card binding docs.
So it could be nice to have them as well. But they should be optional
unless SSI is selected as a CPU DAI.
